Ummmm, I wasn't being mean, I was trying to be helpful by giving you the link to the information you required and then politely suggesting your do a search for any information you may require as there is a LOT of information on this forum.
If you're not sure how to do a search, you just enter what you want to find out in the little box on the top right hand of the page next to the word search and it brings up lots of different threads that can help you find the information you may need.
The first time i applied, it took 3 months. I had to do them again because they will expire by my interview date and this time around they took about 6 weeks.
