While on vacation in the US last year, my wife and I was in a traffic accident. My wife had to spend more than a week in hospital before we could fly home. Our insurance is covering everything, but we keep receiving more bills in the mail. We are forwarding the bills to our insurance company, who tells us that they are taking care of them, but they are probably not paying them immediately (I expect there are a lot of paperwork involved). We can see that some of the invoices have strange addresses on them and have taken a long time to reach us, so we are a bit worried that there might be others that haven't reached us yet.
Also, since the accident was partly my fault, I received a ticket for careless driving, which I have paid.
We are going back to the US in a few weeks on vacation. Can any of this give us problems in immigration or elsewhere? Is there anything we should do or special papers we should bring?
