Get in here on visa upon arrival, and GET a JOB! Unless your wife is one of the top seniors in her company, she unlikely will allowed by the Government to sponsor yourself. On the other hand, you plan to work here anyway, don't you? So get a job and get sponsored by your company. But my advice, start looking for a job NOW, while you are in US. You might get much better offer, than when you are in Qatar. And remember to negotiate the offer, no matter how good it looks.
