Student Dependant - Switch to Graduate Visa - Time of Absence

[hanif54]

Hi. There are 3 parts to my query. I am a PhD student on a student visa which expires on 30 April 2026.

1. I intend to register my fiance as my dependant when we get married this November 2025. We intend to apply for dependant in December 2025. When approved, she will come to the UK in January 2026. Is there going to be an issue considering the short time left (4-5 months) on my student visa?

2. I secured a job in the UK which requires me to obtain a graduate visa in January 2026. When my partner arrives in the UK in January 2026, can both of us immediately switch to Graduate Visa? Or is there a certain period the dependant has to be in the UK before applying for it?

3. Since she has commitments back at home country, she intends to leave the UK right after obtaining the Graduate Dependant. May I know how long she could be outside the UK without affecting her Graduate Dependant status when re-entry later?

It would be amazing if someone could answer these. Thank you.
