When do I have to land after receiving CEAC or NVC from America?

There will be a date of issue and a deadline on the immigrant visa. Generally, the date of issuance will be the day when you face-to-face sign at the Guangzhou Consulate. From that day on, this immigrant visa is valid for half a year, which means you can land in the United States within half a year. The green card production cycle is 1 to 1.5 months, and it will usually be sent to your American address (if not, you can leave an American friend's address for your friend to send back to China, and so on). The green card is valid from the day you land in the United States with an immigrant visa. After getting a green card, it depends on what kind of immigrant you are. If you immigrate through EB-5 investment or marry an American citizen, the first green card you get is two years. At the age of 1 year and 9 months, you need to submit a form to change it into a 10 green card, and the immigration bureau will not approve it until certain conditions are met.
