Does "employment" mean employing an employee as an employer or seeking a job as an employee (or could mean both?)
From U.S.A. immigration forms, 8 CFR §214.1(e):
A nonimmigrant in the United States in a class defined in section 101(a)(15)(B) of the Act as a temporary visitor for pleasure, or section 101(a)(15)(C) of the Act as an alien in transit through this country, may not engage in any employment.
As used here,
engage in employment means
to be hired as an employee. The converse would be unacceptable -- consider a temporary resident being unable to hire someone to fix plumbing in his home, or a mover to bring her furniture to a new residence.
