Girl and boys its true Interpol will be informed if you didnt pay your debt of course not for small amount.

When I was working in Qatar 2 years ago I didnt know that company dont prolong my contract and I left the country but I never, never even think to not pay my obligations.
Be sure they will trace you whenever you are and you will pay your debt or get prison.

I will come back also soon in Qatar and allready inform my bank where, for who and how much is my salary.

This is the only one and the honest way if you use money from bank, get loan or so... give back or one day someone will take your money and ask yourself how you feel?

Best regards to all of you, work and live honest. Life is nice, short and full of wonders.
