ask your employer to provide you a visit or business visa for the mean time so that you can go here. tell the immigration at the philippines that your purpose of travel is just a visit so that they will not ask for OEC, contract, etc. when you arrived here, your company will take care of the transfer of your visit visa into working visa, and thats the time they will ask for your NOC. otherwise, tell your employer to provide a contract for you, go to POEA and get an OEC attend PDOS and get medical certificate. goodluck...
