For US visa, should you take the physical examination first or after?

Legal analysis: First conduct a physical examination, and then carry out the relevant procedures with the physical examination report.

Legal basis: "Exit and Entry Administration Law of the People's Republic of China" Article 9 Chinese citizens shall apply for passports or other travel documents in accordance with the law when leaving or entering the country. Chinese citizens traveling to other countries or regions also need to obtain a visa or other entry permit from the country of destination. However, this does not apply unless the Chinese government has signed a mutual visa exemption agreement with the governments of other countries or if the Ministry of Public Security or the Ministry of Foreign Affairs provides otherwise. Chinese citizens who enter or exit the country as seafarers or work on foreign ships must apply for a seafarer's certificate in accordance with the law.
