I am moving to the USA next year to take up employment. I will arrive two weeks before I begin my work. I need health coverage for the two weeks between arrival and my employee health benefits begin. I would also like to have typical travel insurance benefits for my outbound trip. It seems there is a product called 'One way travel insurance' which gives me exactly what I need, but only a company called 'Go Walkabout Travel Insurance' provides it. Is this something I can request from other companies, ideally ones I might have heard of? My family and I are all UK resident, registered with UK GPs and have no pre-existing health conditions.
Update: The problem here is that standard travel insurance policies do not cover travelers who are not planning to return. I can't point to a online source for this but, for example, I called Insure and Go to confirm this and was told that a standard policy would expire 24 hours after passing US customs if I did not intend to return to the UK.
Where can I find an insurance for my need?
