How do American graduate students get a green card?

Yousi believes that there are three main ways to get a green card: 1. Get a green card through family: international students marry Americans after graduation or American spouses or green card holders can get a green card. Spouses with green cards have to wait nearly five years to get a green card. 2. Get a green card through employment: After graduation, American students can apply for a green card with the support of the company when they look for a job in the United States, are hired by American companies, or are sent directly to the United States by large companies. 3. Get a green card as an outstanding talent and national interest exemption: international students, outstanding professors or researchers, or managers or executives of multinational companies who have been certified by the state as having extraordinary scientific, artistic, educational, commercial or sports abilities after graduation can apply for a green card, which will be reviewed by the immigration bureau.
