What dual degree options are available at the university, and is there a possibility to extend my stay by doing research or pursuing a PhD?

Yes, many U.S. universities offer dual degree programs, allowing you to earn two degrees at the same time - often faster than pursuing them separately. These programs usually require meeting the specific admission criteria for each participating school.

You can also extend your stay in the U.S. after your master's by enrolling in a PhD program or taking up research opportunities. This will typically involve applying for a new student visa or updating your current visa status, which is subject to change based on U.S. immigration policies.
