The bottom line here is no US Airline will consider you for sponsorship since it is a lenghtly process, either via the EB category or H1-B category. If ever you do find a sponsor, you would still be shouldering the legal fees of the sponsoring company (don't ask me how I know)
The best and the cheapest way is to write your own EB2-NIW case, wait for the approval and arrive in the US as a Permanent Resident, again don't ask me how I know.
Otherwise if you are one of the lucky ones, you can join the Diversity Visa Lottery.
