I need some advice

Well you need not be scared, we have many pharmacists here with accents, many from all over the world. Math teachers also with accents and from all over the world. If you look for a job in the larger cities you will have a great deal of competition but to your favor you won't have to worry so much about having an accent and being a minority so it might boost your self esteem a bit. Truly though I don't think you should worry so much about where you are from as the US has become a pretty open place when it comes to "minorities" although I never did understand why people from other countries were called minorities anyway? Plus we do have discrimination laws to protect you from that. I think you should do whichever job will suit you best. Whichever one you will be happy with, because the one you will be happy with is the one you will have the most success in.
