I've got until 27 April to arrive for it to be stamped for a year. I'm married to a Thai national and we have a 3 year old daughter. You can get both single and multi entry the problem is the borders are closed so I believe they are issuing single entry. Then go to your local immigration center for further updates. Good luck
I had my flight from last February 2020. ASQ I also booked to go with the flight same time I applied for visa.
As I stated I went over the top with the documents but I'm that desperate to leave the UK permanently. Enclosed photo of RTE instructions what to do next hope it helps. Good luck

I'm not saying you need all these but I wanted to cover myself. Got my passport back in 5 working days passed Non O single entry 1 year. They send you a letter stating you can now apply for the Certificate of Entry and what is needed. They were very helpful and fast for me. Good luck in your travels
