Full retirement age is the age at which a person may first be eligible for full or unreduced retirement benefits.
There is something else about Retirement Benefits Plan, is it that kind of benefits I will apply when I retire?
Correct. Plus, you can apply for those in cases when you get disabled or death occurs.
Umm, i would prefer to avoid that last one, but is good to know the criteria. Say, what can i do if i already have a significant amount of Social Security credits, allowing me to qualify?
