Nonimmigrant Worker Classifications

Temporary worker classifications only — H, L, O, P, E, TN and R. Each case arrives as a narrative file summary with the employer, the role, the country, the prior employment history and the form of record folded into the prose. Nothing is revealed until you commit.
