immigration policy
There is no compulsory quarantine for entry into the United States in 2022, but nucleic acid testing and COVID-19 vaccine are necessary. International students need to be fully vaccinated before entering the country, and they must be vaccinated for 14 days before leaving the country.
Note that the calculation time of 14 days here is the first day after you complete COVID-19 vaccination, that is, the first 15 day after vaccination.
The day before I flew to America, I had a nucleic acid test and got a negative nucleic acid test report. When entering the country, you need to hold a valid negative nucleic acid certificate within 24 hours and a vaccination completion record of 14 days.
Transit students should check in advance whether there is a nucleic acid testing point at the transit airport and whether an appointment is required.
You need to do nucleic acid testing and self-test within 3-5 days after entering the United States to reduce unnecessary going out before the results come out. If symptoms appear, medical isolation is needed.
Different from throat swab commonly used in China, nucleic acid detection in American universities can be divided into saliva detection and nasal swab detection, and some students usually need to use self-test kit for DIY operation under the supervision of school doctors.
The US government sets the community level of COVID-19 according to the severity of the epidemic in different regions:
Vaccine demand
According to the latest announcement of the US Centers for Disease Control and Prevention, vaccinators should confirm that they meet the following conditions according to the type of vaccination before they can be regarded as complete vaccination:
Single dose vaccine: 14 days after vaccination with the vaccine approved by FDA or authorized by WHO;
Two doses of vaccine: 14 days after the second dose of vaccine approved by FDA or authorized by WHO;
Clinical trial vaccine: fully vaccinated with the vaccine approved by FDA or urgently approved by WHO (after non-placebo 14 days;
Mixing and matching: after any two doses of vaccine approved by FDA or authorized by WHO 14 days.
Precautions:
The interval between two doses of mixed vaccine should be at least 17 days. At present, the CDC in the United States does not recommend mixed vaccines. But this strategy is becoming more and more common in many countries, so the CDC in the United States will accept the approved mixed vaccine.
14 days algorithm: it takes 14 days to board the plane to the United States. For example, my last injection was 65438+1 October1,and 65438+1October 15 met the requirements of 14 on the first day. At present, the vaccines accepted in the United States are China BIBP/ Sinopharm (Chinese medicine vaccine and Kexing vaccine.
