can i change my s2 visa to s1 and what are the requirements?

Kwesi, it’s possible for you to change the X2 type to X1 type. Those documents are needed: your passport, the application form affixed with a passport-style photo, valid temporary residence registration form, health report, proof of your financial support, an admission letter from the school, JW 201 or 202 form as well as other documents required by the consular officers.
