You can earn up to a maximum of four credits per year.
I see, but my disability doesn't make this less complicated. Can you give me a proper example?
Sure. If you become disabled at age 27, you would need 3 years of work 12 credits out of the past 6 years between ages 21 and 27.
Now that is a good example, thank you. And how many credits do I need for survivors benefits?
