Gloria,
re : Filipino maid contract renewal
Fill in the DH contract (4 copies), ask her to check with her "sisters" what they have to bring along to Philippines Consulate (eg your HKID copy ? your tax bill ? proof of address). Tell her to pay for all costs 1st, you pay her back the admin fees paid to Philippines Consulate. (Can be done on Sundays, Ph Con also opens on Sundays.)
After Ph Con has endorsed your "new" contract, either you go or she goes to Imm Dept, another set of forms to fill in - for DH employment, and DH visa extension. Maid can go alone to Imm Dept and wait for min 1hr45min max half a day to get DH visa for new contract.
If you trust her with your photocopies, you can ask your maid to do everything. Some ppl put all the photocopies in sealed envelopes, mark confidential, to be opened by Imm Dept and Imm Dept will seal whatever should be returned to you. You need to pay visa fees ($1xx) and the DH tax ($2400 for 1st half-year if you want to pay by instalment).
Can get a set of forms for you and let you have it next Monday when we exchange goods, if you want.
