Is there any new policy from Shanghai to San Francisco?

Do a good job of nucleic acid detection within 72 hours in advance, and you need to apply for customs code before entering the security check.

1. Do the nucleic acid test within 72 hours in advance. It should be noted that the nucleic acid test must be an institution that can issue a report in both Chinese and English and attach a passport number (translation is invalid). You can go directly to Chinese and English nucleic acid testing institutions for testing, and just search online.

2. Arrive at the airport at least 4 hours in advance. Although there are fewer people on international flights at the airport now, due to many uncertainties during the epidemic, it is still necessary to arrive at the airport as soon as possible. When waiting in line, the airport staff will issue a letter of guarantee that needs to be signed. Be sure to bring pens, because there are many forms to fill out, and it is inefficient for everyone to borrow pens.

You need to apply for a customs code before entering the security check. The process of customs clearance is smooth and simple. Apply for customs code, and roughly fill in your health status, home address and nearest place.

There are not many people at the boarding gate, because the domestic epidemic prevention and control is well done, and masks must be worn well. Remember to put the nucleic acid report and passport together, because the airport staff will check it many times.

Get on the plane. Because there are not many people going to America now, there are basically one person on the plane. Before you get off the plane, you need to fill out three forms, one is the health declaration form of New York State, and the other is the declaration form of e-mail, name and contraband, but no one reads it when you leave the customs.

6. enter the customs. Due to the epidemic, not many people entered the United States. The immigration officer didn't ask any questions and left no fingerprints. 7. The key is: you don't need to be isolated when you go back to the United States, and you can move freely immediately after you go out.
