@LinaJ2020 that is understandable, however, I have already been in the use on student or trainee visa for 5 years and 2020 will be my 6th year. There is an exception to the 5-year lifetime rule for students:

The questions is whether I can apply and use the exception for students for the days in 2020 I was on F1 if I have changed my F1 (student) visa to H-1B (non-student) on October 2020?
Thanks,
