Please help - brother's UK visit visa got refused
My family are intending to visit the UK to attend a graduation and staying another 2 weeks for tourism. My parents have already got 10 year visas but my brother's visa got refused. He is:
- Pakistani national
- UK Graduate in Computer science - 2021
- Had post study work visa but left the country in July 23 as he did not find work.
- Currently works in Saudi Arabia, stable job, has been working there for over a year and intends to go back after his visit to continue working.
His mistakes:
- He submitted 1 year of bank statements (dont know why!!!!)
- He didn't mention that he's also attending our sister's graduation ceremony in the UK.
I am helping him re-apply through the urgent route and need some help covering the refusal points. Any help with wording and application points would be appreciated. Thank you
