Hi to all , can all of guys help me out to decide for one of my friend who wants to move to hungary & ready to invest there about 300,000 euro to get permanent residency through their program(residency bond program) , i needs views from all of guys & especially from those who already did this process , & if they can share with me their experiences and can let me know what are the advantages or dis advantages for this program , because we really do not know about this , and as per hungarian program this 300,000 euro will be deposited in bank i think for 5-years and after 5-years these will be return to provided account and they will also charge 60,000 euro separately for process fees , and this 60,000 euro is non refundable , so please give me your views , really will appreciate for  your information
