U.S. Immigration

Envoy’s easy-to-use online platform provides complete visibility into the immigration process for everyone involved—from the HR manager to the sponsored employee. And you can be confident that every case is managed by attorneys who focus solely on U.S. immigration law.

With nearly 20 years’ experience managing the immigration process for enterprise companies, Envoy’s affiliated attorneys prepare quality work visa petitions in an efficient and transparent way. All legal work is covered by a flat fee, so there are no hidden costs or ongoing hourly billing.
