 Hi. So, I got my 214, Social Security card, my passport, a ball of my blood, and my first born. Choosing to opt in to the new blended retirement system is probably easier than you think. No red tape, no blood tests, no first born child. Depending on your branch of service, you simply go to one of these designated resources and sign up online. We'll make it easy for you to choose your financial future and hers. And that's a fact. And that's a fact.
