Hi Everyone,
I was issue dependant visa, family 10yrs route because of my daughter 2yrs 6months and when that expired , change to spouse visa, The route was not sated in the decision letter. then when biometric was faced off and register for evisa which now showing my status as dependant . My question is this as follows:

1, do I have to change the status to spouse visa?
2, I know for spouse is 5 yrs before indefinite, do I have to count the 5yrs from the date of marriage? or from the date of first visa issued? or from the date of spouse visa issued?

3, with all this in mind, when can I apply for indefinitely to remain or British citizen?
