Depends. If you have assets in US the Automated Collection System may be able to take part of what is due. If you want to go back to US depending on the amont you owe, it can be taken from property sells and can go up to US taking your passport (the US one only obviously), thats a recent rule and applies only if you owe more than $50k.
