California’s independence will never deprive you of your United States citizenship – you will simply become eligible for dual citizenship in California and will be living in a foreign country. The good news is that won’t affect your retirement benefits. The Social Security Administration says that U.S. citizens living outside the United States may continue to receive retirement payments “as long as you are eligible for payment and you are in a country where we can send payments.”
By the way, collecting your Social Security retirement benefits as a U.S. citizen living in another country also means you will still be automatically covered by premium-free Medicare Part A if you visit the United States and need additional coverage while there. You will also be eligible for coverage under Part B. In short, you will not lose your citizenship, your health insurance coverage, or your Social Security retirement benefits by voting yes on the California independence referendum.
Additionally, an independent California will be well-positioned, financially speaking, to implement a universal, single-payer healthcare system, which has been estimated to cost Sacramento between $50-$100 billion in additional spending each year. We will be able to afford this as an independent country without raising taxes because we won’t be contributing to Washington’s bloated military budget.
