Some of my documents for the UK Visa consist of 2 or 3 pages so I stapled them. But I've read online that when you submit your papers on your appointment day, your documents should not be stapled, is that true?
Don’t staple sets of different documents into one big pile but if the pages make up one single document it’s perfectly normal to have them stapled.
You don’t want to carry a 50 page bank statement as 50 lose pages of supporting documents. That’s a single document and it does need a staple/clip.
