I don't think its going to be healthier decision and the state will face tremendous brain drain in the recent future. this law would make the country a house without ventillation.
Qatari national economy is booming in an indescribable pace however a new law like this can create major damages in all levels. people leave everything behind and come to work in this state due to many reasons like family, career prospects, financial stability, etc. etc. and its normal to find people looking for better oppurtunities or investment plans. i know there are many in this state are willing to invest if they get release without any ban!! may be you loose one today but tomorrow you will find many others with better thoutghts and ideas.
when other states in the GCC have flexible rules and regulations then why are we trying to make it complicated? this strategy will never bring an innovative work force into the state. loads to say... no time.
lets hope to have a favourable decision from the government.
