You have been told by another more knowledgable member exactly how this might be tracked.
But I'll play: if you think it can't be tracked, are you ready to have to go through the mess of proving that you were out of the country for less than 30 days after they stop your benefits? You can't have it both ways.
Here's the thing: the point of the rules is that you are to maintain a presence in the US. You endanger that be trying this stunt.
You are going by the
layman's version of the rules. There are frequently more subtle rules addressing the actions of those trying to game the system. I would consult a legal specialist, or better yet, the SSA, before trying this.
