How can my friend obtain a pension statement for a Tourist Visa application in Thailand?

What country is he from?

I just use the bank statement that shows my state pension payment never had a problem with that

I just went through getting a marriage visa through the online portal. I have a state pension from Oregon. All I had to do was go to my portal on the state pension website and they had a statement much like my bank statement indicating what payments they have made and when. It was available for download as a pdf. So you might check to see if your state pension office has such a portal.

I recently got a tourist visa, they ask for a lot of stuff which is confusing, but basically just upload a bank statement and in the section that asks for self assessment as one option, I typed a letter using Microsoft word stating I wasn't on a pension and no one invited me was the other one, somewhere in there they ask for a letter from the person who invited you, anyway I uploaded a bank statement

In the UK you receive a new state pension statement each year, for your new increased pension.

This is what I upload.

He can get a state pension statement from the DWP. Maybe even online

I would just upload a blank page written on it “NO PRIVATE PENSION” you have to submit something -

as long as he has the funds on his bank statement. Return flight. The application comes back quite quick approval in about 5 days. However if they want more info they send an email then there’s a delay by about four days in them answering again. so he needs to leave himself enough time applying- Just incase. Otherwise like someone said, just come in on 30 days stamp and extend.

He would have had a have a letter from DWP saying how much state pension he gets.

Where is he coming from and for how long ?

He doesn't need a pension for a tourist visa. Just upload a bank statement showing more than $5k usd.
