I have a question for my friend who lives in the UK

He recently joined a dating site TLL and has been in contact with a Thai lady from Ubon Thani. Apparently they seem to be getting along and have been exchanging texts and been in regular contact over the last few weeks. However she is now wanting to travel to the UK to see him. I have told him to be careful but it's not really my business. She apparently has a passport, her husband died recently, but she has been asking for bank statements from my friend, and photos of his house.

My friends position is as follows. He is unemployed as he now looks after his 2 young children, as likewise his partner passed away just over a year ago. He is 36 years old and is on benefits for caring for his children, and dissability benefits for a hearing problem.

My question is this. Assuming the Thai lady has a passport of some sort, and assuming their relationship is going to blossom into something wonderful, what is required, if possible to enable his Thai GF to travel to the UK.

Cheers
