How can I get a residency for US

One of the ways to immigrate of course is through employment-based sponsorship. The question in your case is what type of permit you have to work in this country. If you are here on a nonimmigrant visa such as H-1B for specialized worker or L-1 as an intracompany transferee, the organization would likely be able to sponsor you for your permanent residence and you would be allowed to adjust status in the States so long as you continue to maintain your legal status. On the other hand, if you previously violated your status and only now have an employment authorization document (EAD) from U.S.C.I.S., you may be ineligible to adjust status even if the company sponsors you and you obtain both labor certification and completion of the next step, the I-140 petition. You may wish to consult with an experienced immigration lawyer prior to investing time and money into this type of application. There are of course other ways to immigrate, but a proper answer would require further information on your background.
