Its not really necessary but it would still end up your own decision if you decide to withdraw it on bulk amounts but if you are not on a hurry then you can gradually withdraw those amounts on small portions.Immigrating into other countries is too much hassle on me and i dont really feel like on leaving my fellow country for the sake of cashouting those funds yet there are lots of ways on how you would able to pull out those but though you would really have restrictions but its really possible.
