VISA FOR MY WIFE AND SON

[belfast2016]

Could anyone please help me giving advice concerning my wife's and son's visa?

I've recently got ILR visa. Prior to getting ILR, I was on Tier-4 general student visa. However, my son (Born in June 2005 in Bangladesh) and wife came to this country in June 2008 as my dependants. They have still visa valid until 28 June 2017.

At this situation,
1. through in which route can they apply for visa?

2. What application form should I use for them?

3.Is £18600/= income applicable in this case?

Regards,
Rahman
