Thanks for the great service you are rendering to the public. The forum has been of immense help to thousands.
My son, an H4 student, will graduate in May 2021 but be 21 years old in Dec 2020. So he needs to change H4 to F1, & he plans to do so in summer 2020.
1- Can I just apply to his university with required financial docs, and my son can go to India to get F1 stamped? Do we need to fill in any forms (other than those required for the visa interview at the embassy)?
2- If F1 at the embassy is denied, will it affect his H4 status?
3- If F1 is denied, and on his arrival from India, we apply for COS - does his existing H4 status freeze?
