I'm engaged to Ana who lives in Brazil - we've been together online since 2014 and she's visited me here in the UK a couple of times. We're hoping to get her here to the UK on a Fiance Visa later this year (2022). But we have some issues working out the best timeline for it all and was hoping someone might give some advice.
The wedding's booked for here in the UK on 5th Sept 2022 (although date could be changed for smallish admin fee).
Ana took and passed the IELTS A1 English Language test back in March 2020 before Covid hit in Brazil - so that expires 2 years later (doesn't it?) - 2 years will be 6th March 2022.
But, for other reasons, it would be tricky for Ana to leave Brazil before May at the earliest.
So I'm thinking it would be best for Ana to take the English test again - or even to take the A2 test which I believe would mean she wouldn't have to take it again after the first 2 and a half years (3 years counting the 6 month fiance period) of her being here. Is this correct?
My main worry here is if we apply for the visa Feb 2022 at latest (which we'll need to do if Ana doesn't take another English test to be before the 6th March expiry date) - if the visa's granted quickly then Ana might have to travel here before May.
My main question is - we saw (when doing a practice 'dummy' run through of the visa application form) that it says once the visa is granted Ana would have just 30 days to arrive in the UK before her visa expired. Is this still the case? Because, in a Whatsapp group Ana belongs to, she was told that due to the pandemic this 30 days has been extended to 3 months. Is this correct?
Thanks in advance to anyone who can give us any help here.
