With more than 20 years of experience and thousands of cases in complex US work visas and immigration matters, I represent domestic and international businesses to hire or transfer employees authorized to live and work in the United States. I also represent individuals to obtain work authorizations and permanent residence (green card) in the US. My practice focuses exclusively in investment and employment related visas (E, H, L, O, P, NAFTA) for professionals, executives, scientists and artists, as well as investor/trader visas (E1/E2) for nationals from bi-lateral treaty countries. Permanent residence through employment offers (EB1 to EB-4) and investment (EB5), as well as derivative visa and immigration for family members.
