US Immigration Attorney in NY - OUR SERVICES


If you wish to pursue your career or full-time study in the U.S., you will need a non-immigrant visa for which you need to meet certain criteria. In general, a work visa requires a sponsorship from a U.S. employer and we file a visa petition on behalf of the employer. A company that plans to conduct businesses in the U.S. also needs to obtain a non-immigrant (or immigrant) visa. Our firm provides legal services to individuals who plan to obtain non-immigrant status to work or study in the U.S.; companies planning to conduct businesses in the U.S.; and U.S. companies that plan to hire non-immigrant/immigrant employees.


Green card holders can live and work permanently in the U.S. as permanent residents without any restrictions imposed under non-immigrant visas. Some green cards (i.e., EB-1A, EB-2 NIW, EB-5) may be self-petitioned without a sponsorship from employers, but others (i.e., EB-1B, EB-1C, EB-2 Perm, EB-3) require U.S. employer’s sponsorship. Also, family-sponsored green card requires a sponsorship from a family who holds a green card or citizenship. We provide legal services for employment-based/family sponsored green card petitions to individuals who plan to obtain/sponsor permanent resident status in the U.S., companies planning to conduct businesses in the U.S., and U.S. companies that plan to sponsor a foreign national employee for a green card.


Lawful permanent residents in the U.S. can obtain citizenship through a process called naturalization when they meet certain criteria. Our firm provides legal services to clients who are permanent residents and plan to obtain citizenship in the U.S.
