Is there a law to be implemented January of 2014 that will hold a % of the money you can send out of the US and will there be a limit on the amount you can send out of the US?
No such law in existence or planning. There are no limits on what you can transfer in or out of the USA, as long as you're not doing tax evasion/money laundering, or violating embargo laws against specific countries and organizations.
Explanation why Rob's answer is wrong:
There's no, and never has been, withholding requirement when transferring money between own accounts.
FATCA doesn't impose any new withholding. It reinforces the existing 30% withholding requirement, and suggests that the 30% withholding requirement may supersede treaty positions. Generally internal legislation cannot supersede international treaties, so I'm very skeptical about the US Gov't ability to enforce this.
30% withholding on payments to foreign people/entities has always been there. It's not new. Certain payments that are income sourced in the US and being remitted to foreign payees is subject to 30% withholding (unless treaty says otherwise). There's nothing new about it, been like that forever.
