What visa are you currently on?

I have just received a spousal visa, I did it through an agent and thank goodness that I did as she had to go to the home office in Pretoria about 7 or 8 times and had to queue for about 1.5hrs each time.

Agents can be very helpful as they deal with all the red tape and also know the system, and sometimes the correct people to talk to. (I am not talking about bribing, they just know who to speak to if there are any problems).

Good luck
