Congratulations and welcome to world of legal US immigration. You are better off scouting the Mexican border. Dealing with US immigration is b-school admissions multiplied by 10. Make sure you start early and provide the right documentation the first time. Things get easily lost/delayed...just a heads up.
We are starting the process now with hopes of getting approved by the end of the year. Yes, US immigration sponsorship is a major pain in the a$$, and that's coming from a bonafide citizen.
