I'm an international student, and my F-1 visa is about to expire. Can I stay in the U.S. and continue my studies?

You'll need to apply for an F-1 visa extension or renewal through U.S. Citizenship and Immigration Services (USCIS) before your current visa expires 

You may be eligible for Optional Practical Training (OPT), which allows you to stay in the U.S. for up to 12 months after completing your studies
