How long is the validity of the medical examination of American immigrant visa?

The medical examination of American immigrant visa is valid for half a year. You must enter the United States within 180 days after the medical report comes out, otherwise the US Immigration Service will not recognize the medical report. Therefore, whether the visa is approved or not, it will take more than half a year to re-examine before entering the United States.

For major immigrant countries such as the United States, the Immigration Bureau has designated specialized agencies to be responsible for immigration physical examination, including supervising the immigration physical examination network, appointing physical examination doctors, and recommending inspection items. Other countries, such as Singapore and Britain, require immigrant applicants to submit health certificates, which can be issued by hospitals at or above the county level and qualified doctors. The physical examination of immigrants from Australia and other countries depends on the different types of visas. Some countries need to evaluate whether the elderly over 75 can withstand several hours of air flight, and some countries require local schools to issue immunization certificates for the children of applicants. According to the requirements of Australia, all applicants for immigration, study or visit (except short-term visa applicants under the age of 74) must undergo a medical examination and meet the requirements before obtaining a visa.

Remind applicants who immigrate to the United States that the US Consulate General in Hong Kong requires all applicants to have a medical examination by an approved doctor before the visa interview, because the medical examination will expire after a period of time. Applicants are advised to arrange a physical examination no later than four weeks before the visa interview date and issue a report in about one week. Applicants should bring unopened reports to the interview. According to American immigration law, immigrant visa applicants must be vaccinated to get an immigrant visa.
