planning to get married to a work permit holder, I want to know based on those that have experienced my situation on how does the process go? any way to hasten the approval time?

All you need to do is get your documents ready before hand. Your spouse's birth certificate, education certificates and letter of employment. Preferably get them translated into English (if they are still in their native language). Get the approval for marriage with MOM. Submit them via ICA's website and just wait patiently. You only have control over how fast things get done on your side, ICA/MOM works pretty fast if all the documents are in place.
