Please do explain me this also...i known some people who lives in USA illegal,,but now they are citizens of US withouh getting married there....or working with any US company...And is it true that,,,police wont arrest illegal people until they does some crime..And if i legally stay there with non-immigrant visa,,,what are the possibility to become a permanent resident there.

Answer:
Almost impossible to get a green card from that situation. That's why there are so many illegals in this country.
In 80's there were amnesty from congress and President Reagan. Many people took that chance to become legal aliens
In general, local and state police won't arrest illegals unless there are crime. That job is belong to ICE.
I guess no one wants to help you break the law.

However, to one of your points, it is NOT true that illegals are only arrested if they commit another crime. Even if you live in a sanctuary city you are subject to ICE raids. About 1200 were picked up at a single company just before Christmas, for example.
