Being a non-US citizen, your employer will save some payroll taxes (basically FICA). This is probably not very relevant in your case, as most good employers are looking for great people, not savings. Besides, savings are minimal given your salary levels.

In some occasions, employers might get away with hiring a foreign person paying a lower salary than to an equivalent American. This is basically an illegal practice, but they can eventually get away with a minimal saving.

Do not attempt to exploit this advantage.
