With the passage of the monumental Frank-Dodd financial reform bill in the U.S., forex brokers that had moved accounts overseas to avoid some of the new regulations in the U.S. are required to move them back to the U.S.
This will affect people that tried the FXCM experiment and moved their accounts to FXCM UK. FXCM is required by law(along with other forex brokers that used the same loophole) to move those accounts back under the jurisdiction of their US offices.
So if you have an offshore forex account with a forex broker that has US offices, be prepared. You should receive a letter from your broker soon (if you haven't already) that the account will be migrated to the US office.
This is just another round of regulations for the forex industry that will probably have very little impact, other than irritating traders.
