My name is jihad and my brother’s name is talib, would that effect our visa application to US and Germany or anywhere else ?

Yes, “jihad” and “talib” are real personal names in the Muslim world, our names existed long before taliban movement or the modern western stereotypificafion of “jihad”.

Having spent a lot of time on reddit lately, i got used to people cursing my name occasionally, but i wonder if this might have a real effect on a visa application or something
