I would like to take my long term girl friend to England for 10 days. I'm paying for her trip I'm a bit confused with filling out the finance section of online form.

I'm confused with these below questions, however question 3 is the most confusing. I don't know if this is the total cost she will spend of her money or the total cost of the trip with our combine finance

If there is absolutely no cost to her then put zero and explain in the covering letters, say if she's paying for any of her incidentals.

If you are financing 100% of the trip then provide evidence that it's affordable for you to do so and that's it's reasonable for you to do so.

It's imperative that she provides evidence of her ties to Thailand and thus her reasons to return, and, I note you are posting from Thailand, your joint ties, if any.

Ok thank you
