Can I get a green card when studying for a doctorate in the United States?

You can't transfer to a green card during your PhD. You can get a green card with your work visa after you have to work.

For most students studying in the United States, in order to obtain a green card, the general practice is to find a job after studying in the United States, change their F- 1 student status to H- 1B employment status with their employers, and then apply for a work permit from the Ministry of Labor through their employers. After the work permit is approved, apply to the Immigration Bureau for immigration with the priority of the second kind of occupation. Apply for a green card after the immigration application is passed.

His professional work and achievements show that his application for immigration to the United States conforms to the interests of the United States in economy, society, environment, culture and medical care. Individuals with special abilities can be exempted from national interests and do not need to apply for a work permit from the Ministry of Labor.

Some people with F- 1 student visas can apply for immigration in this way, whether they are teaching assistants or doing postdoctoral research.

J visa green card application

Visiting scholars with J- 1 visas to the United States must return to their own country to live and work for two years after completing the scheduled study and research projects in the United States before they can apply for permanent residence status in the United States, which limits the ways for such people to obtain permanent residence status to some extent.
