When travelling, the safest and most legally accepted “Invitation Letter” is in the form of an Affidavit of Support or Guarantee (AOSG), sometimes called Affidavit of Support with Undertaking.  This looks very much like a regular Invitation Letter- all details are there- but with written in a more legal and formal matter. Most importantly, this must be authenticated and legalized by any Philippine Embassy or Philippine Consulate General in any Schengen Area.

What is an Affidavit of Support and Guarantee?

The Affidavit of Support with Undertaking is a legal document that states that the inviter who is living abroad will shoulder the trip expenses of the visitor in part or in full, and that the visitor you will be under their responsibility during the stay in that country.

STEP 3: Once notarized, have it authenticated by the relevant District Court.

STEP 4: Pay €22.50 (or around €27.50) for each document via bank transfer (if submitting the documents via mail) or in person during your appointment at the Consular Office.

Note: For updated rates on authentication of documents, please check the specific Philippine Consular Office in the Schengen Country where you will apply for an AOSG.

STEP 5: Mail in or hand deliver your documents to the Philippine Consulate or Embassy. Make sure to include one photocopy of each document as well as the proof of payment.

STEP 6: Once the documents have been submitted, the Philippine Embassy/ Consular Office will process the documents within 7-10 business days.
