My boyfriends working holiday visa is up in September, and he intends to go on a student visa, but I’ve read that you can’t apply for your student visa until 3 months before the course starts, or 4 months before it your overseas (courses start in feb 2019) which means there’s a 5 month gap between September and February, does that mean he will need to leave the country for roughly 2 months before he can apply for a student visa & then get a bridging visa to come back into the country??
