Hi all:

I have an approved I-140 but will be losing my H1B status end of this month (04/30). My wife is on an F-1 visa. I was wondering whether I can switch to an F-2.
My having gone through the I-140 shows that I have an intent of immigration. Can I revert back to a non-immigrant visa now?
If going into F2 is feasible, what are the costs involved? When should I start the process?

You guys have been great and supportive in answering these testy questions. Your responses will be much appreciated.
