P.S The employer may be unfamiliar with the process if you are thier first foreign hire.It's relatively cheap painless but can be time consuming in the sticks several vist to offices where the senior officials are too bsy to clock in on golfing days.

Do try and ask them or the employer how many docs pix etc beforehand nearly all govt offices have a copy shop nearby as there is an endless pile of copies by little officers afraid of poo yais

Good luck
