I appreciate the quick response. This website is a great resource. If only the information given to me by the Home Office was as clear. It was not stated very clearly that I should expect to be stranded in the UK for 6 weeks after becoming British. In fact, they seem to take pride in the fact that the naturalisation can be done without having to surrender my original passport. As with everything in this country, there has to be useless bureaucracy somewhere along the way. I never should have expected otherwise.
I have an American passport. It seems unlikely that an airline would attempt to stop me from boarding a flight to the UK? I don't recall them having any issues when I have travelled in the past and I have not usually shown them my BRP when boarding flights.
Unfortunately the coronavirus does not allow everyone to put life on hold. I have business in the US and do not have the option to re-schedule. In fact my trip to the US later this month might lead to us moving there permanently. If that is the case I guess I will have to apply for my British passport from abroad. Ironically, if I apply from the US, I don't have to send in my passport, but only colour copies.
However we may be in a situation where we need to travel back to the UK a second and third time in the first month that we are in the US. I guess if that happens I will just have to take a chance. I am British, I have lived here for nearly 10 years. I have two British children and a British wife. I cannot imagine a scenario where I would be denied entry.
Does anyone have any direct experience with this? I cannot be the only person who has made this mistake?
