Who provides travel insurance for a 60-year-old who's already left the country?

Q) My mother-in-law has already arrived in the USA from the UK and, due to various complications, needs to buy travel insurance. US companies can't insure her because she's not a US citizen and all the UK companies we've found won't because she's already started her trip. Worldwide Insurance does this but only for those aged 59 or under and she's nearly 61! Who can help?

A) NO one is going to give you travel insurance AFTER the trip has started. That's the way it works. Otherwise, it's just like trying to bet on a horse race after it's started. Can't do it. She'll have to do this uninsured.
