My sister is an American citizen. Can I apply for a green card before entering the country?

My sister needs to submit an immigration application and wait for approval before entering the United States. If her sister enters the United States before submitting an immigration application, she may be regarded as an illegal immigrant.

When applying for immigration, you should submit the application materials to the immigration bureau or relevant institutions and pay the application fee according to the regulations. The Immigration Bureau or relevant agencies shall review the application materials, conduct interviews or background checks when necessary, and enter the country after approval.
