Rudolf, Maybe you or your wife could get a a graduate degree from a university here. I think there is a provision that people with such degress are allow to work here after their completion and eventually become citizens. However, it may be limited to certain areas(I think it is) that are highly competitive for admissions. Maybe either one of you doesn't have any degree, than you could just enroll in any community college and work towards one. It would at least give you a good four or five years. Here in California, community colleges are cheap even for foreigners. I'm taking a math class at my local CC, I would say at least 25% are foreign students. From the conversations I had with some of them, they appear to be doing similar to what you want to do. There is even an older French lady, older than you, in the class.
