Two totally different things. You ask about visa, all info available from your embassy. Food hotel costs and anything else has nothing to do with visa's.
Here in Udon Thani the same. Most people seem to keep wearing the masks. Personally when outside never wear one, when inside a shop or mall then I am happy to put one one on just to be polite.
says if you are using UK bank statements it is the last 3 months of statements with each one showing an excess of £10,000. That's what I had to provide when I made my application last December.
The last couple of times I have applied for a single entry non o E visa in the UK this was a requirement. The reason for visa was being over 50. First application was pre covid. The second one earlier this year. Both times uploaded the bank statement as requested, visa issued within 3 - 4 days.
