hello aspirant,

Firstly caste certificate of any year is valid only after telangana and ap seperated.If you have caste certificate before that kindly apply one.If you have the cerficate after is bifurcation no problem you can take that for certificate verifiaction because the caste doesnt change unlike income cerficate.

The only thing that you need to get updated is income cerficate because it may change every year.income cerficate must be updated as for after jan 2020.

hope this helps

thankyou
