Uk visa
Hello, i need your help regarding my visa application
Age: 24 yo
Country: Jordan
Visa: standard visa
Status: unemployed and single
I need your advice, I need to apply for a visa to give an exam (ORE exam) in the uk my sponsor is my brother (he has 4k pounds) and I don't have enough savings(almost 1k pounds) in my bank account so my all family is here and I am living with them
The exam provider will give me a visa sponsor letter for the exam and I will be going only for 5 days I can insert a document that I'm enrolled with a course since 6 months to study for the exam
I have been to the uk before and got back home with no violation
I have a good travel history and had Schengen visa before but I got one rejection of Schengen visa as well I have never overstayed or something in any country I have been to
What are the chances and what things I can do to improve my visa application?
Thanks in advance
