Hepatitis B can't immigrate to America.

Whether you can get an American visa has nothing to do with whether you are a carrier of hepatitis B virus. You don't need a medical form in the materials required to apply for an American student visa, so even if you are a hepatitis B virus carrier, it won't affect your getting an American student visa.

However, schools in the United States need to submit a physical examination form when they report for duty, so I suggest you go to the entry-exit inspection and quarantine bureau to check your hepatitis B virus type before you report for duty. As long as it is not an infectious virus, you can still enter school normally.
