I'm moldy. I don't know if I'm cured. I want to apply for an American visa now. I don't know if it's ok

You can get an American visa. Rest assured! But you must wait until you are well before you can go to America. Syphilis may be contagious. Those who travel for a short time may be exempted from inspection, but those who stay for a long time must apply for the International Travel Health Certificate. If syphilis is not cured, the International Travel Health Care Center will not send it to you, so you can't go abroad. But syphilis is nothing, you can check whether it is cured.
