You are planning to work abroad, as a salesclerk, office assistant, hotel manager, domestic helper, seafarer, factory worker, etc.

What are necessary documents that a Filipino OFW will need: (As years of working in a recruitment agency i managed to learn some of these tips)

Passport:

You will be needing your Birth Certificate (PSA copy), Marriage Contract (PSA Copy) for married woman

Note: PSA is formerly NSO

If your NSO copy is handwritten or illegible (hindi masyadong mabasa) you will also be needing your birth certificate from the Local Civil Registrar (munisipyo).  
You should get one because some Embassies require this copy to be attached together with the PSA copy upon submission for attestation/legalization.

Most employers require an NBI clearance for your employment abroad, so you might as well get one (this may also serve as additional I.D.s for your passport application)

DFA usually asks for two (2) Valid I.D.s (should be any of the following):

• SSS I.D.
• Company I.D. (kung saan ka kasalukuyang nagtatrabaho)

• Driver's License (better keep LTO O.R. because some offices usually ask for the LTO official receipt so might as well save your O.R. just in case)
• Other Government Issued I.D., like GSIS e-Card, UMID Card, etc.

• Voter's I.D.
• PRC License I.D.
• old Philippine Passport

If you only have one valid I.D., other I.D.s may be presented as additional identifications (any of the following):

• Old Company I.D.s
• Old Student I.D.s
• Voter's I.D.

• TIN Card
• PhilHealth ID

Other supporting documents that may also be presented to the DFA are:

• Transcript of Records (contains data which includes date and place of birth)
• Baptismal Certificate (contains data which includes date and place of birth)

• Voter's Registration Record (data includes date and place of birth and sometimes with picture of the person)

• Diploma
• Yearbook (Highschool or College) contains data which includes picture of person and date of birth

• copy of marriage contract (can be additional supporting document for married male applicant)

Especially if you have discrepancy on data in your birth certificate as opposed to the data in your I.D.s and school records, it is best to bring all supporting documents that you have if you can, so as to avoid denial of your application and being advised to come back only after complying with additional documentations.
