Thanks everyone.
The American British passport relationship allows the British passport to be valid 6 months after it expires when travelling to or from America. Singapore requires six months on the passport whilst transiting through there.
I have a new permanent resident visa from last September . It is a digital visa that digitally connects with your passport when travelling so its always available when changing passports. And yes i will have to spend time travelling to get a new passport when in the UK.
Regarding using the old passport i did not want to disappoint my young son again with this trip i already had to cancel his family Christmas due to covid and being turned around at Singapore would be depressing. thanks everyone your a great reassuring resource of people that care and are knowledgeable .
We still cant drive out of our rd unless one has a high clearance 4WD . we were stuck for about a month hence the problem. Just for a bit of background we had 50 inches 1300mm of rain in two days. We were flooded in before that. . Im a disability support worker in and around Lismore, 10 of my colleagues lost their houses and everything in them. my central work place was destroyed it employs 300 plus people. My friend had an office 50 feet above the river in Lismore her office was flooded by 1.5metres. 5000 homes went under up to the roof ( two storey) and every shop, servo, supermarket, cafe, restaurant , pub, chemists, all wiped out. We have been through a catastrophic natural disaster. Two years ago we were evacuated due to the bush fires then covid now this.
Thanks everyone have a great day all the best John Tredrea
