change of surname in passport

I have changed my surname in pass port, but i currently hold a visa with my old surname. is there any issue will happen at foreign country?

did you had a retina finger print scan while granting visa?

visa was granted by saudi government.

i'm not remembering about that retina finger print scan!

I think the retina fingerprint scan had taken

No issues if you had the biometrics done.

Sir may i know what is the procedure if the biometric hadn't taken?
