I know u can do it in the UK…but can’t find any insurance agency in the US to do it.
The best thing to do is call a LOCAL independent agent. Look in the phone book for the PIA or Big I (Trusted Choice) logos and they should be able to help you.
In Texas, we have several companies that will write a 30 day policy – but that is the LEAST amount of time for issue.
If you are hear as a tourist, you can purchase coverage on a rental car. I have had foreign workers that come and find it more cost effective to purchase a car for the period they are here and then sell it when they return to Europe.
In that case, 30 day policies would probably be what you need. You could always start a 6 month plan on payments and then just quit paying when you leave the country.
Good luck and I hope this helps!
