From the link above updated 10/17/2013. Does this mean no transfers to the US?
Only if your name shows up on the OFAC list. Unless you are a suspected terrorist (or something similar), it shouldn't. If you are really curious you can search it your self online.
The OFAC disclaimer has nothing to do with their ongoing international wire issues.
