An Affidavit of Support and Guarantee is usually needed when a Filipino traveler, visa applicant, or minor child must prove that another person will pay for the trip and take responsibility for the traveler’s stay abroad. In real life, people often ask for it because a relative abroad is sponsoring a tourist trip, a foreign partner is inviting a Filipino to visit, a child is traveling with someone other than a parent, or a foreign embassy wants proof of financial support. The document can help, but it is not a magic paper: it does not automatically guarantee visa approval or departure clearance at the airport. Philippine immigration officers still look at the traveler’s documents, purpose of travel, financial capacity, travel history, and overall circumstances. (Philippine Embassy Berlin)

What Is an Affidavit of Support and Guarantee?

An Affidavit of Support and Guarantee, often shortened to AOSG, is a sworn written statement where a sponsor says, under oath, that they will financially support another person’s travel, stay, accommodation, food, airfare, medical or emergency expenses, and return to the Philippines.

You may also see similar names:

Affidavit of Support
Affidavit of Support and Undertaking
Affidavit of Support and Consent, especially for minors
Affidavit of Support, Guarantee and Consent to Travel, depending on the Philippine Embassy or Consulate form

For Philippine outbound travel, the Bureau of Immigration and IACAT materials commonly use the phrase Affidavit of Support and Undertaking, while Philippine embassies and consulates often use Affidavit of Support and Guarantee in their notarial forms. The practical purpose is the same: to show who is sponsoring the trip, what the relationship is, what the sponsor’s financial and immigration status is, and why the traveler is going abroad. (Philippine Embassy Berlin)

When Do You Need an Affidavit of Support and Guarantee in the Philippines?

You usually prepare an AOSG in these situations:

Situation	Is an AOSG commonly needed?	Practical notes
Filipino tourist sponsored by a relative abroad	Yes, often	Especially if the traveler has limited personal funds or is a first-time traveler
Filipino tourist sponsored by a foreign boyfriend, girlfriend, fiancé, friend, or employer abroad	Often	Expect closer questioning because the sponsor is not a close relative
Filipino traveling with a local sponsor from the Philippines	Sometimes	A notarized local affidavit may be presented, but it does not control the BI decision
Minor Filipino traveling abroad without a parent or legal guardian	Often, plus DSWD clearance	AOSG is separate from DSWD travel clearance
Visa application before a foreign embassy	Depends on that embassy	Some embassies require their own sponsor form or proof of funds instead
OFW leaving for employment abroad	No, not as a substitute for OFW documents	OFWs need proper DMW/OEC and verified employment documents, not a tourist AOSG

For ordinary Filipino tourists, the primary documents under the IACAT departure guidelines are a valid passport, visa when required, and round-trip or return ticket. The affidavit becomes important when the traveler is sponsored or is referred for secondary inspection. (Philippine Embassy Berlin)

Legal Basis in Philippine Law

The legal background of the AOSG comes from several areas of Philippine law.

First, the 1987 Constitution protects the right to travel, but the right may be regulated in the interest of national security, public safety, or public health as provided by law. The Supreme Court in Genuino v. De Lima, G.R. No. 197930, April 17, 2018 emphasized that the right to travel is a constitutional liberty and cannot be restricted by an unsupported administrative issuance alone. (Lawphil)

Second, outbound passenger screening is linked to the government’s anti-trafficking mandate. The current anti-trafficking framework comes from Republic Act No. 9208, as amended by RA 10364 and strengthened by RA 11862, or the Expanded Anti-Trafficking in Persons Act of 2022. These laws explain why immigration officers screen for possible trafficking, illegal recruitment, fake tourism, and vulnerable travelers. (Lawphil)

Third, DOJ Memorandum Circular No. 036, series of 2015, listed by the Bureau of Immigration as the IACAT Revised Guidelines on Departure Formalities, specifically mentions affidavits of support or undertaking for sponsored passengers. It states that if a passenger is traveling through a sponsor, the affidavit should show the sponsor’s relationship to the passenger, financial capacity, legal status, and contact information. (Bureau of Immigration Philippines)

Fourth, an affidavit is a sworn statement. Under the 2004 Rules on Notarial Practice, the person signing must personally appear before the notary and be identified through competent evidence of identity. A false sworn statement may also expose the signer to perjury under Article 183 of the Revised Penal Code, as amended by RA 11594, which increased the penalty for perjury. (Lawphil)

Finally, the “guarantee” part has a civil-law meaning. Under Article 2047 of the Civil Code, a guarantor binds himself to fulfill another person’s obligation if that person fails to do so; under Article 2055, guaranty is not presumed and must be express. This is why the affidavit should clearly state what the sponsor is promising to pay or shoulder. (Lawphil)

Who Can Be a Sponsor?

A sponsor may be a Filipino or foreigner, as long as the sponsor can prove identity, address, legal status, relationship or reason for sponsorship, and financial capacity.

Close relatives

The IACAT guidelines refer to sponsors within the fourth civil degree of consanguinity or affinity. In plain language, this includes close family relationships such as:

Parent, child, spouse
Grandparent, grandchild, sibling
Uncle, aunt, niece, nephew
First cousin
In-laws within the relevant degree, such as parent-in-law, sibling-in-law, or similar relationships by marriage

The guidelines give examples such as pinsang buo for consanguinity and bayaw, hipag, or biyenan for affinity. (Philippine Embassy Berlin)

Non-relatives and foreign sponsors

A non-relative can sponsor, but the traveler should expect more scrutiny. A foreign boyfriend, girlfriend, fiancé, friend, company, or family friend should be ready to show:

Clear reason for sponsorship
Proof of relationship or prior communication
Sponsor’s passport or government ID
Sponsor’s residence permit, visa, or legal status abroad
Proof of financial capacity, such as payslips, bank certificates, tax documents, or employment certificate
Invitation letter and travel itinerary

If the sponsor is a company, foundation, school, or other legal entity, registration papers and proof that the signatory is authorized should be included. (Philippine Embassy Berlin)

How to Get an Affidavit of Support and Guarantee Step by Step

1. Confirm why the affidavit is needed

Before drafting anything, identify the exact purpose:

Airport departure as a sponsored Filipino tourist
Foreign visa application
Minor’s travel
School, training, conference, or visit invitation
Support for a foreign national’s Philippine-related application

The purpose matters because the format and authentication route may differ. A foreign embassy may have its own required sponsor form. The Bureau of Immigration may look for an AOSG only as part of the total circumstances of departure. A DSWD minor travel clearance has separate requirements.

2. Use the correct form or format

If the sponsor is abroad, check the Philippine Embassy or Consulate that has jurisdiction over the sponsor’s place of residence. Many posts provide their own AOSG form and checklist. For example, the Philippine Embassy in Berlin requires a filled-out AOSG form, sponsor ID or passport, traveler passport, proof of relationship, and proof of financial capacity such as payslips or bank documents. (Philippine Embassy Berlin)

If no official form is given, the affidavit should normally include:

Full name, citizenship, civil status, date of birth, and address of sponsor
Sponsor’s passport or ID number
Sponsor’s immigration or residence status, if abroad
Full name and passport details of the traveler
Relationship between sponsor and traveler
Destination country and travel dates
Purpose of travel
Specific expenses the sponsor will shoulder
Undertaking that the travel is for the stated purpose
Undertaking that the traveler will return to the Philippines, when applicable
Sponsor’s contact details
Signature over printed name
Notarial or consular acknowledgment

3. Gather supporting documents

Prepare documents before the sponsor signs, because consular posts often pre-screen the packet.

Document	Usually required from	Why it matters
Passport or valid ID	Sponsor and traveler	Confirms identity
Traveler’s passport bio page	Traveler	Matches affidavit details
Proof of relationship	Both	PSA birth certificates, marriage certificate, photos, messages, or other proof
Proof of sponsor’s legal status abroad	Sponsor abroad	Residence card, work visa, PR card, citizenship card, or similar document
Proof of financial capacity	Sponsor	Payslip, employment certificate, tax return, bank certificate, bank statement
Invitation letter	Sponsor	Explains reason, address, dates, and travel plan
Travel itinerary and return ticket	Traveler	Shows temporary travel plan
Hotel booking or accommodation details	Traveler or sponsor	Shows where traveler will stay
Company registration or authority	Juridical sponsor	Needed if a company or organization is sponsoring

4. Have the affidavit notarized or consularized

The correct signing route depends on where the sponsor is located.

If the sponsor is abroad

The safest route for Philippine outbound travel is usually to execute or acknowledge the AOSG before the Philippine Embassy or Consulate covering the sponsor’s location, especially when the immigration guideline or consular post specifically asks for embassy or consulate authentication. Philippine posts may require personal appearance, appointment, pre-assessment by email, original documents, photocopies, and payment of consular fees. (Philippine Embassy Berlin)

In Apostille Convention countries, another route may be available: the sponsor signs before a local notary public, then obtains an apostille from the competent authority in that country. The Philippine Embassy in Washington, D.C. explains that private documents such as affidavits may generally be notarized locally, apostilled by the competent authority, and then used in the Philippines. Requirements vary by country or state, so the exact post or competent authority should be checked before relying on this route. (Philippine Embassy)

For non-Apostille countries, documents generally still go through local notarization or authentication by the host country authority and then authentication or legalization by the Philippine Embassy or Consulate. (Philippine Embassy)

If the sponsor is in the Philippines

The sponsor may sign the affidavit before a Philippine notary public. The notary should be a commissioned notary in good standing, and the sponsor must personally appear with a valid government-issued ID.

A Bureau of Immigration FOI response clarified that an AOSG “duly authenticated by the Philippine Embassy or Consulate” does not apply when the sponsor is based in the Philippines; that requirement refers to a sponsor located in the destination country. The same response also emphasized that a notarized AOSG or simple letter from a local sponsor does not substantially control the departure decision, because immigration officers assess the totality of circumstances. (www.foi.gov.ph)

5. Send the original and keep digital copies

The traveler should carry the original notarized, consularized, or apostilled affidavit if possible. Also keep scanned copies on the phone and cloud storage. At the airport, documents are easier to assess when they are complete, consistent, and immediately available.

6. Prepare the traveler’s own documents

An AOSG is only one part of the travel packet. The traveler should still prepare proof that the trip is genuine and temporary, such as:

Valid passport
Visa, if required
Return or round-trip ticket
Itinerary
Accommodation details
Certificate of employment, approved leave, school certificate, business registration, or proof of ties to the Philippines
Personal bank documents, if available
Sponsor’s AOSG and supporting documents
DSWD clearance for covered minors
CFO documents for covered emigrants, spouses, fiancés, partners, J-1 visa holders, or au pairs

BI has announced streamlined CFO requirements: Filipino fiancés, spouses, and partners of foreign nationals holding tourist visas are no longer required to undergo the CFO Guidance and Counseling Program, but GCP remains required for Filipinos departing with immigrant or long-term permanent residence visas, fiancé, spouse or partner visas, J-1 visas bound for the United States, and au pair visas bound for Europe. (Bureau of Immigration Philippines)

Special Rules for Minors Traveling Abroad

A minor is generally a person below 18 years old. A Filipino minor traveling abroad alone or with someone other than a parent, legal guardian, or person with parental authority may need a DSWD travel clearance in addition to any affidavit of support, consent, or guarantee. DSWD explains that travel clearance is intended to prevent abuse, exploitation, and trafficking of children. (DSWD CAR)

Common minor-travel documents include:

PSA birth certificate of the child
Parents’ valid IDs or passports
Child’s passport
Affidavit of consent and support from the parent or legal guardian
DSWD travel clearance or certificate of exemption, when required
Passport or ID of traveling companion
Proof of relationship with traveling companion
Sponsor’s financial documents

Do not treat an AOSG as a substitute for DSWD clearance. If the child falls under DSWD rules, immigration officers may still stop departure even if the sponsor has a notarized or consularized affidavit.

Fees and Timelines

Fees and timelines vary depending on where the affidavit is executed.

Process	Typical office	Practical timeline
Local notarization in the Philippines	Notary public	Often same day if documents and IDs are complete
Consular acknowledgment or authentication abroad	Philippine Embassy or Consulate	Depends on post; some require appointment and pre-assessment
Apostille abroad	Competent authority in country/state of execution	Varies widely by country
DSWD minor travel clearance	DSWD MTA system or DSWD office	Separate process; apply early before travel
DFA apostille in the Philippines for Philippine documents used abroad	DFA Office of Consular Affairs or consular offices with authentication services	Depends on appointment, document type, and release schedule

As an example, the Philippine Embassy in Berlin lists a €25 fee per document for AOSG authentication, regular processing of five working days, and express processing of two working days for qualified personal-appearance applications. This is only an example; each embassy or consulate has its own fees, holidays, appointment system, and documentary checklist. (Philippine Embassy Berlin)

What Immigration Officers Usually Look For

At the airport, the issue is not simply “Do you have an AOSG?” The better question is: Does your whole travel story make sense?

Immigration officers may look at:

Whether the declared purpose matches the visa, ticket, and itinerary
Whether the traveler can explain the trip clearly
Whether the sponsor’s identity and relationship are credible
Whether the sponsor has legal status and financial capacity
Whether the traveler has reasons to return to the Philippines
Whether the traveler appears vulnerable to trafficking or illegal recruitment
Whether documents are genuine, consistent, and not tampered with

Under the IACAT guidelines, secondary inspection may consider age, educational attainment, financial capability, travel history, and country of destination. Automatic referral concerns include minors traveling without required clearance, passengers with no financial capacity accompanied by a foreign non-relative, travel to countries with deployment bans or high alert levels, and previous long stays abroad as a tourist or temporary visitor.

Common Mistakes That Cause Problems

Using a tourist AOSG for hidden employment

If the real purpose is work abroad, do not use a tourist affidavit to make the trip look like a vacation. Filipino workers need the proper DMW/OFW process. The IACAT guidelines separately require OFW documents such as passport, valid visa, travel ticket, and OEC for departing OFWs.

Submitting a weak affidavit with no supporting proof

A one-page affidavit with no ID, no proof of income, no proof of relationship, and no travel details is weak. The affidavit should be supported by documents that make the sponsorship believable.

Relying on a foreign boyfriend or girlfriend’s invitation alone

A foreign partner can sponsor, but the traveler should prepare more than romantic messages. Bring proof of relationship history, travel itinerary, accommodation, sponsor’s ID and financial documents, and proof that the Filipino traveler has ties to return to in the Philippines.

Forgetting that embassies have different rules

AOSG requirements in Germany, Japan, the United States, UAE, Singapore, and other countries may differ because consular jurisdiction, local notarization, apostille rules, appointment systems, and fees differ. Always follow the Philippine Embassy or Consulate with jurisdiction over the sponsor’s residence.

Thinking the affidavit guarantees departure

The Philippine Embassy in Berlin expressly states that allowing a Filipino tourist to depart is under the authority of Bureau of Immigration port officials, not the Embassy; the Embassy’s role is to authenticate the AOSG upon submission of requirements. (Philippine Embassy Berlin)

Signing without personal appearance

A notarized affidavit signed without personal appearance can be challenged. Philippine notarial rules require personal appearance and competent evidence of identity. False statements in an affidavit may also create criminal exposure for perjury. (Lawphil)

Frequently Asked Questions

Is an Affidavit of Support and Guarantee required for all Filipino tourists?

No. For ordinary tourist departure, the basic primary inspection documents are a valid passport, visa when required, and return or round-trip ticket. An AOSG is commonly needed when travel is sponsored or when the traveler is referred for closer inspection.

Can a sponsor in the Philippines issue an AOSG?

Yes. A sponsor in the Philippines can sign a notarized affidavit before a Philippine notary public. However, BI has clarified that the embassy-authenticated AOSG requirement refers to a sponsor located in the destination country, and that local sponsor documents do not automatically determine departure clearance. (www.foi.gov.ph)

Does an AOSG prevent offloading?

No. The more accurate term is deferred departure, not “offloading.” An AOSG may help explain sponsorship, but immigration officers decide based on the totality of circumstances, including travel purpose, documents, financial capacity, travel history, and trafficking indicators. (www.foi.gov.ph)

Does the AOSG need to be apostilled?

It depends on where it was signed and how it will be used. If signed abroad, the safest route for Philippine airport purposes is often consular acknowledgment or authentication by the Philippine Embassy or Consulate. In Apostille Convention countries, a locally notarized and apostilled private affidavit may be usable in the Philippines, but the traveler should check the specific Philippine post and receiving office. (Philippine Embassy)

Is “red ribbon” still required?

For DFA authentication of Philippine documents for use abroad, the old red ribbon system has generally been replaced by apostille for countries covered by the Apostille Convention. For foreign documents used in the Philippines, apostille may also replace Philippine consular authentication if the document comes from an Apostille country, subject to exceptions and receiving-office requirements. (Apostille.gov.ph)

Can a foreign boyfriend or girlfriend sponsor a Filipino tourist?

Yes, but expect closer scrutiny because the sponsor is not a close relative. The traveler should bring a complete and consistent set of documents: AOSG, sponsor passport or ID, proof of legal status, proof of income, invitation letter, itinerary, proof of relationship, and proof that the Filipino traveler will return to the Philippines.

How recent should the AOSG be?

There is no single universal validity period for all AOSGs. In practice, use an affidavit prepared close to the actual trip, with travel dates, destination, and sponsor details matching the ticket and itinerary. Many travelers prepare it within one to three months before travel to avoid questions about stale information.

Do minors need an AOSG?

Sometimes, but an AOSG is not enough by itself. A Filipino minor traveling alone or with someone other than a parent or legal guardian may need DSWD travel clearance or a certificate of exemption, depending on the circumstances. (DSWD-MTA)

Can an AOSG be used for a visa application?

Yes, if the foreign embassy accepts it, but many embassies have their own rules. Some require a specific sponsorship form, proof of accommodation, tax documents, employment documents, or bank statements. The AOSG should match the exact visa category and purpose of travel.

Key Takeaways

An Affidavit of Support and Guarantee is a sworn sponsorship document, not a guaranteed visa or airport clearance.
For sponsored Filipino tourists, the affidavit should show the sponsor’s identity, relationship, legal status, contact details, financial capacity, and undertaking to support the trip.
If the sponsor is abroad, use the Philippine Embassy or Consulate process, or a valid apostille route where accepted.
If the sponsor is in the Philippines, a notarized local affidavit may be used, but BI still assesses the whole travel situation.
Minors may need DSWD travel clearance in addition to any affidavit.
Do not use a tourist AOSG to disguise overseas employment.
The strongest travel packet is consistent: passport, visa, ticket, itinerary, proof of funds or sponsorship, proof of relationship, and proof of return ties all tell the same truthful story.
