Conversation Between BigJoe5 and gopo

Hi
I wonder if you could help me with some questions.
I hold H1 visa, I had that for 5 years, and I am considering starting my own business. I was under the impression that a physician could start his own office in underserved area on H1 visa after completion of 3 years employed on guaranteed salary. This H1 visa is expiring and I cannot extend that with my employer due to expiration of contract and inability to pay. My green card application is being denied. If I start my own business who is supposed to help me to get a green card.
The other question is if I buy a house USCIS may be more interested to help me to get naturalized and if I decide to return to my country, I have some savings, I need to take my savings to my country. Am I supposed to pay tax when taking large amount of money to overseas?
Thank you very much for your time and understanding.
