What should I do if my immigration to the United States fails to pass the medical examination?

Generally speaking, American immigrants can pass the physical examination, and the requirements are relatively relaxed. So immigrant applicants don't have to worry too much. However, under the following circumstances, the US Immigration Service is very likely to refuse the visa: 1, infectious disease; 2. Not vaccinated; 3. Physical or mental disorders; 4. Drug abuse or drug addiction In order to prevent serious health risks from threatening the health of the American public, USCIS may refuse foreigners' green card applications. However, applicants who are found not to meet the health conditions can apply for exemption if they are rejected for certain health reasons, and USCIS also has the right to grant exemption in this case.
