A TRV is a visitor visa, no distinction whatsoever in this context. Use the one you were pointed to.Thank you for your reply! the second portal basically uses the term visitor visas and it doesn't use the term TRV anywhere, whereas the first one use the term TRV.
Is there anyone in the group who has applied for TRV for a spouse and let me know which portal to use for spousal TRV. A link would be helpful. thanks
