So does this mean they're now being flexible on the rule about not applying more than three months before intended travel?
I think this is the first time in over 10 years, I've seen anyone be granted a visa that starts more than 3 months in advance. But who knows.
It's such a dysfunctional system, cannot apply more than three months before in process that takes 3-5 months from beginning of application, then given less than one month for people to up and leave jobs, accommodation, family, pack up and ship stuff etc which all need notice, planning, preparation.
It does keep changing.
Back when I first joined the forum (when spousal visas were valid for 2 years only and you applied for ILR at the end of the 2 years), the spousal visa sticker was valid for 24 months and while you could enter the UK at any time in the 24 months, if you left it more than 28 days from the valid from date, your visa would expire before you could qualify for ILR, which meant you had to apply for an FLR(M) extension to bridge the gap.
Then they changed it so that the spousal visa sticker was valid for 27 months, giving you a leeway of 3 months and 28 days to enter the UK and still qualify for ILR before the visa expired.
When the new rules came in in 2012, and it was changed to 5 years for ILR (30 months on the spousal visa, 30 months on FLR(M)), you were issued with a 33-month spousal visa sticker, and you had 3 months and 28 days to enter the UK and still be okay for FLR(M) and ILR.
Then in May 2015 they changed it again so that the 33-month spousal visa was issued as a BRP collected in the UK, and your visa sticker for entry into the UK was valid only 30 days.
