US Employment visas
Work permits for the U.S. are available across many categories, and may be subject to annual quotas and complicated regulations. Many occupations lead to visas quickly due to the shortage of skilled workers in the U.S. Others require visas that can take a long time to acquire and may involve several federal agencies in the process. Some employment visas are temporary, some are permanent. Others begin as temporary but do allow the individual to pursue permanent residence.
