Keeping the green car and resident status
Dear attorneys, I recently received the green card, but i do business mainly in my home country and travel to the US twice in 6 month for 2 weeks. I file tax return (but have no income in the US), and i rent a small place where my mail comes (cell phone bill, bank statement, etc). For how long can i keep this up, because i do not want to lose the residence status? I love the US, it's just my income source is attached to what I do in the homeland. Should I stay more than 2 weeks during each 6 month period? thank you.
