No. But your age and marital status, as well as legal status of your parent will determine which category you get placed into:
Under 21, unmarried, child of USC: IR
Over 21, unmarried, child of USC: F1
Under 21, unmarried, child of LPR: F2A
Over 21, unmarried, child of LPR: F2B
Any age, married, child of USC: F3
There is no category for married children of LPRs.
So you can be a 50 year old divorced child of an LPR and get petitioned into F2B.
