Well, if you get the UK visa before you travel then yes you can! That would save you getting separate visas, as if you were to get the irish visa before you left to fly into Dublin you would need a separate UK visa then to fly to the UK so your best bet would be to try and acquire the UK visa and fly into Belfast and just get the train down as you said, you're killing 2 birds with the one stone as they say with the visa for the uk
If you get the UK visa you can visit Ireland through the north and come down but I know if you are coming from Ireland to the UK you definitely need a separate visa for the UK. My wife and I live in Ireland and we had to make a trip to the embassy in London to renew her passport during covid and there were no such facilities in Ireland at the time. We applied for the visa and were waiting about 2 weeks and she was granted the visa to travel to England. To apply for the visa we had to go an office in dublin that handles the visas for the UK for a interview to answer a few questions and bring all the paperwork with us
No ! You get a 60 day stamp in your passport in the airport at immagration that you can extend by another 30 days at any local immagration office if you wish to stay up to 90 days
really ? Who provides the visa in her passport ,does it have to be sent to England for to be done or what?
I know when my wife came to Ireland (I know a different country) but alot of the time we have similar rules and ways , when her visa was approved we had to go to the embassy in bkk and they attached it to a page in her passport. Sorry for the misinformation on my part
