Well, guess every one saying without knowing the rules with all my respect, Dear its all about the claim if your cerdit card is due and your bank already claim it in kuwait that mean even you can not fly from kuwait. but if still u have some pending amounts and its still valid acctive i mean your credit card so easly you can fly and stay years and years without facing any challange, if same time you are paying it on monthly basis as per your bank rules and condations. bottom line if there is a claim so this is the only challange you may face it here in Qatar to enter but if not NO WORRIES. wish you all the best and wishing a great luck in Qatar. so my advice is to you if your credit card over limited pay what is over satnding if you can not effort to pay all but without knowing of your bank that you wont be back to kuwait and once you reach here you can pay it its just like if you have a credit card pending amount you can fly dubai bahrain or even doha for example for a vaction.

and people please give adivce when you are 100% sure abt it.

cheers
