Where you should go depends on severity of disease. If you are seriously ill, you should go to an emergency department at a hospital. (If you had a primary doctor in the US, they might be able to admit you directly without going through the ED if you were very ill.) If you are ill and need to be seen soon, urgent care centers exist and they should be able to see you quickly. If you are well enough to wait for a few days-to-weeks, then you can schedule an appointment with a doctor. How it is paid for depends on insurance status. I don't know whether your home country has national insurance, how that works once you're in the US, or whether you personally have private insurance. If you are not insured in any way, then you could be liable for expenses. Finally, it seems unlikely that a doctor would write you for antibiotics without seeing you first, but who knows.
