I came in America with my J 1 student visa and in order to stay legal I've applied for tourist visa in October and i received the response of it : ( we mailed you a denial decision notice for this case I539 APPLICATION TO EXTEND OR CHANGE NON IMMIGRANT STATUS . The notice explains why the denial decision was made and the options that may be available to you . During this step the formal decision ( approved / denied ) is written and the decision notice is mailed and / or emailed to the applicant / petitioner . You can use our current processing time to gauge when you can expect to receive a final decision . ) And my question is what i should do in this situation ? apply again or is there any situation that i can remain legal in America ?
