EAD validity EB2 vs EB3

Is there any difference in EAD validity period when applied in EB2 vs EB3? I heard someone mentionining that we get 3 year validity in EB2 vs 1-year in EB3. Is it true?

In general, are there any differences in EAD issued under EB2 vs EB3?

Thanks,
MSR

I485 EAD has a validity of 1-2 years. I don’t think EB2 or EB3 category makes any difference.
