I think it really depends on the location of the company and if the company
has potentials. (1) If they sponsor you, you get status--> move onto the
next one with better pay and benefit. (2) Compare your salary with what your
friends got and the locations of the companies. Maybe, $7=$9 of your
friends. (3) boss is important. If you ran into a mean boss or a boss you
dislike, you would prefer a boss with lower pay and happy environment. (4)
Experience is very important in U.S. Currently, the job market is still very
tight.
Final decision is up to you. Perhaps a good idea to talk with your
adviser or friend in the profession and get their advice and opinion.
Bottom line: don't miss an opportunity.
A piece of advice: one bird in hand is worth of two birds in the woods.
Not sure if you have other potential offers.
