Excuse me, will it affect the visa for studying in the UK after getting the American i20?

A visa only means that you are legally qualified to enter a country. You go to the United States to study first and get an F- 1 visa. Then you went to an English university as an exchange student for a year. At this time, you must get a Tier 4 visa again. The end result is that you have both an American F- 1 visa and a British Tier 4 visa.

There is no conflict between the two. A visa only means that you are legally qualified to enter a country. Being able to enter country A does not mean that country B will not be allowed to enter at the same time. So, don't worry about this problem at all.

Basic information

An American study visa is a visa to study in the United States. American immigration law provides two kinds of non-immigrant visas for students studying in the United States. The "F" visa is issued to international students studying in the United States.

The "M" visa is issued to international students who are engaged in non-academic or vocational studies. To obtain a student visa, an applicant must first apply and be accepted by an American school. When you are admitted, the school will send you an I-20 or I-20M form. You must show this form when you come to apply for a visa.
