Hi Elizabeth, yes, he "jumped the gun" it seemed as he was expecting his Spanish citizenship to roll in and it was tax season in the US afterall.
It was also good (though I didn't mention it in the article) that his wife was a Spanish citizen, so the man wasn't destitute. But, banking is definitely an obstacle.
Besides, the IRS is one of the single most powerful entities in the world.
Many banks in many countries won't even open a bank account to US citizens due to treaties that allow the IRS to examine any US citizens bank account in any bank in any country that has this treaty.
Renouncing citizenship is a very serious issue and should never be taken lightly or on a whim just because a person doesn't like whichever political party happens to be in power, social or cultural issue happens to be going on at a particular time.
Of course this is a deeply personal and individual decision, but should never be taken lightly...
Politics and society change, but getting rid of US citizenship is permanent...
