Let me help you, to prove that you will get back to you home country in any TRV visa, do following:
- Give them bank statement where you are getting money from last several months
- If you are married, leave your family behind this will make strong ties to home country due to family
- Give them you job details
- Give proofs of any property on your name
- Car details if you have one
- Any business contract with anyone in partnership
- Slips of rental property or any contract with them
All these things can make the case stronger.
