Quote from billyjoerob:
I think you're underestimating how little the USCIS cares who you are. Renunciation is not a joke. You WILL NOT come and go as you please after handing in your passport.
This is from ycombinator:
"A person who renounces U.S. citizenship is generally not able to take advantage of the special visa programs (like the EB5 investor program) to regain residency. Furthermore, their applications for visas, etc., are also (informally) put in the lowest-priority bracket unless they pony up to be placed in the priority queue.
Moreover, any attempt to renounce their renunciation of citizenship results in a hefty tax bill for the period they were not a citizen, as the initial renunciation will be treated (by the IRS) as an attempt to evade taxation. Indeed, merely returning to the U.S. for a period of more than 183 days (one of the tests for residence for taxation purposes) could trigger this result."
This is not about taxes at all. It is about never living in the US again. You don't renounce citizenship unless you never plan to live in the US again.
