In view of the above situation, it is illegal. Although you are in senior high school, your student status is still in China, and you passed as an exchange student. So you issued an F 1A visa (so-called I- 10). Now that I graduate from senior three, I need to apply for a community college in senior three. It should be easy. Try to communicate with the community college, send you an admission notice in advance and take you back to China. This is the standard legal way.

There is another way, that is, go directly to the three local embassies for consultation with your high school diploma and community college admission notice, and he will try to make you stay ~ but in the end, you have to go back to China to go through the visa formalities for F 1-B, otherwise the United States will help you sneak in, you have to understand this ~

Also, I don't know if it is convenient to disclose why I can't go back to China to sign. Are you worried that your language scores will be rejected?

Actually, there is no need to worry. Go to the embassy to find a pure white visa. If you have a successful history, the visa rate will be close to 100%.

What's more, you said that two years of I-20 is not desirable. I wonder which community college you went to. If it is a community college in northern Seattle or central Seattle, I suggest you sign more time. You know, even if you complete the credits, if the GPA is lower than 3.5, you can't transfer to Washington University or Johns Hopkins University. Taking more classes for a while can make up for the lack of GPA with credits ~ ~

I hope it works for you ~ ~
