Taken from the Direct Hire Process. Once you send the visa sticker to your helper in the Philippines she needs to do the following.
13. the worker/helper should proceed to the Philippine Overseas Employment Administration (POEA), Name Hire Processing Unit, Household Worker?s Processing Center, located at the G/F, POEA Bldg., (Blas F. Ople Bldg.), corner EDSA and Ortigas Ave., Mandaluyong City, or to the nearest District/Regional Office to submit the endorsement letter from the Labor Attache HK, original authenticated employment contract, visa sticker, plane ticket/TEV and the National Certificate for HSW (NC2 ? on Competency Assessment) from TESDA and Certificate of Competency (on Language and Culture Orientation) from OWWA, together with the photocopy of his/her passport for final processing and issuance of Overseas Employment Certificate (OEC).
14. The worker /helper should also undergo a medical examination in POEA Accredited Hospital or Clinic. The cost of said medical examination should be shouldered by the employer.
15. If all the papers are in order, the worker/helper will be required to attend the Pre-Orientation Departure Seminar (P-DOS) conducted by the Overseas Workers Welfare Administration (OWWA).
16. An Overseas Employment Certificate (OEC) will then be issued to the worker/helper and he/she could now book/confirm her flight to Hong Kong, SAR. The OEC would also exempt the worker/helper from paying the Philippine travel tax and the international airport terminal fee
