Well, if you don't have a work permit for the U.S. I am afraid it is impossible or nearly so for you to come and work in the U.S. Now, let's assume that you do have a permit, do you have FAA certificates? If not, then you will have to convert, which actually means take the written, oral, and practical exams for instrument, commercial, single and multi. A private license will be issued with no exam, but that doesn't do much good it you want to work. So, let's say that you have both the work permit and the FAA licenses, many people do as they may have trained in the US in the past.
Your hours may be a little on the low side but there are still jobs out there which you can compete for. It really depends on what kind of flying you want to do. Single-pilot neight freight, well that's possible since I think you meet the requirements (have to check that though). You could instruct, if you get your FAA instructor licenses. You are competitive for a regional position flying an RJ or turboprop somewhere in the country. Although, you have to remember that there are a lot of pilots in the US who are furloughed, plus the bunch that are finishing their training. So, they are all lining up for jobs and you'll have to compete with them. However, many regional, not major but feeders, are recalling their pilots. So, there is some growth in the middle of the industry pyramid. There are probably jobs available doing other less mainstream work, such as flying jumpers, pipeline patrol, fish spotting, bush flying, etc. Those are harder to find info on and I don't know any good sites.
Hope that helps.
