I'm on F1 and got pregnant. Can I take a break for sometime and get back to studies? My husband is a GC holder..well we got married after he got GC. Now can he apply for a family based GC for me, I kind of know that it takes atleast 4 yrs for me to get GC...but just wanted to make sure that he can apply while I am on F1.

For various reasons, I usually see no point in applying for a green card through a permanent resident spouse while you are on an F-1. About taking a break, the F status requires you to attend school full time unless there is a medical necessity. You need to discuss that with your international students advisor.
