I don,t think so.I believe discrimination can only be affected to a person who is not strong either mentally or phychologically he feels that he is inferior.Now for that matter u can be a victom of descrimination if you have these qualities even if you are professional.
My dear friend always remember when you show somebody that there is something wrong with you only then you are treated wrongly.
I have been to UK, USA , Dubai ,Behrain and KSA and never allowed anyone to misbehave for nationality reasons.
So have faith and forget about any premature fears.Remember if anyone does something wrong its his fault and you should not be affected by this.
