Hopefully

Rubbish. No fixed rule, as long as you come and go and stick to the rules and don't overstay you ok. They may ask why you keep coming back and have a plausible answer. I used to come every weekend from HKG, and never got refused and asked a few times why, explained and never an issue

Tourist visa with you as sponsor. Dead easy , as long as you follow all the rules my girlfriend got her first go as we provided all info in detail.

Reasons for her to return - land and business

Evidence of relationship for last 3 years - used holiday pics

My financial position to support

Snowed em under with paperwork and evidence and worked a treat. 2nd and onward visa haven't been an issue and no longer need extra paperwork

Get a visa first in UK and even that don't guarantee entry, immigration can still turn you back if they see fit.

What can possibly go wrong....

Don't need to be married at all

7-11

Friends, relative address. Keep a UK mailing address and all good

LTR is the way forward as long as you really meet the criteria and will again in 5 years . It's fairly simple and does what it says....I got mine 2 months ago

It says on the visa itself -60 days , then if you want to stay longer need to get an extension from Immigration, do a border run or fly in/out again
