I am resident in GCC country, I will apply for UK tourist visit visa. I have current bank account which I receive the salary through it, and saving account under same bank under my name also, I transfer money between both accounts.
Is transfer between my current and saving account can be reason to reject the visa?
As detailed in another Q&A (UK Visa Refusal: Provenance of funds/parking), your overall financial position and where the funds come from are important to get a UK visa. Some transfers between a savings and a current account would be expected but if it looks like you are trying to obscure where the money comes from or you rely on savings to compensate a salary that's too low to afford your travel or your lifestyle then you may have a problem.
