It is much, much quicker, easier and cheaper to marry in the US as a visitor (which is perfectly fine to do) and apply for a UK spousal visa, than it is to apply for a fiance visa and marry in the UK.
Marry in the US
- you fly to the US as a visitor
- you get married within a couple of days and fly back to the UK (or stay in the US as a visitor for up to 90 days before flying home)
- he applies for a spousal visa
- he moves to the UK and can work and use the NHS for 'free' from day 1
Total visa cost = £1,523 plus £1,200 IHS surcharge = £2,723 (plus your flights to/from the US)
Marry in the UK
- he applies for a fiance visa
- he moves to the UK
- he cannot work or use the NHS for free (so he will need private health insurance)
- you give notice to marry
- you have to wait at least 28 days after giving notice before you can marry... this may be extended to 70 days if your case is referred to to the Home Office (because he has a visa)
- you marry in the UK
- you apply to switch to an FLR(M) visa for him to stay in the UK after the wedding (usually 8 weeks for processing, but may well be longer due to Covid delays)
- once he has the FLR(M) visa, he can finally work in the UK and use the NHS for 'free'
Total visa cost = £1,523 (fiance visa) + £1033 (FLR(M) visa) + £1,000 IHS surcharge = £3,556
