I'm a British pilot working in the US and will say that it is relatively easy to get a job right now if you have the right to work in the US. That means having a US passport or greencard. If you don't have these then it is highly unlikely that anyone would sponsor you for employment.
Try getting a Visa through the greencard lottery they have each year. I don't have details but if you write to the US embassey in your country they will send you details - I think the correct name for the program is something along the Immigrant Diversity program although I'm sure a little research on the web will get the details.
P.S. If you are British ( except NI ) forget this program as you aren't eligible.
