Thanks for
answering my question. I don’t understand why some of you  have to be so arrogant answering to a simple
question. Does Sajha say anywhere you can not ask a simple question? How can I know
it’s relevant or not? The question which is not relevant to you,  can be relevant to others. I asked a simple
question and expected simple answer.  If
you wonder how I got green card, i can say the same, you can check how you can get green card at http://www.uscis.gov. I thought
we could get ideas here. the question which is very simple,  might be very tough one for somebody else. don't be so arrogant my friend?
