Thanks all.
She's coming next week. There's still enough time to send her a few grand, although I'd lose money converting it over and then back again.
I think we'll just let her wing it since everyone says they never got asked to prove if they had any funds.
Yeah - I've given her a passenger arrival card in her language and written instructions on how to fill out the real one (must be done in English).
If they have any queries, they'll be able to ring me and I can translate for her too if required.
I've never heard of customs sending a visitor home - that would be very extreme. Hopefully everything will be fine.
Cheers,
Woody
