@Malcolm ********
I got my non o visa in 4 working days online
All u need is 3 months bank statement (make sure you use the free adobe pdf program and merge all 3 months into 1 file as you can only send 1 file with proof of bank statement) with £1000 in it and showing your salary has gone into that bank account on the statement o am married to a Thai national so I had to show the wedding certificate a photo of myself easy to do on your mobile
Any problems they do come back to you via email and checking the website
Also remember when u do the o line form on the bottom of each page click on save as the website can crash once in a while and it will save you repeating yourself of it crashes
Good luck
Ohh I forgot if you do it in the UK the 1st non o visa is £60 and only apply 1 months before u leave and it’s valid for 3 months
