After reading some posts by the CEO of Bitinstant, they are going to check your name/address in the governments system. If your on it, they will deny your transfer. If your not, it will go thru. They won't hold any funds, they will either do it or not.. BTW, if you want to check to see if your name/address is on the Govts list, here is the CLEARLINK site that you can check.. Warning, this is a clearnet site. http://sdnsearch.ofac.treas.gov/Default.aspx If you dare to put your own name/address in then you can see if you will have a problem or not.. But use that clearnet link at your own risk..
