Hello,

For proforma a1 the Candidates should be residing in the state of West Bengal continuously for the past 10 years as on December 31, 2020.

For proforma a2 the Candidates should be residing in the state of West Bengal continuously for atleast 10 years as on Dec 31, 2020, and the candidates should have passed the 10+2 examination in the year 2020 or before.

As you can see it's Stated that The domicile certificate should be as of 31.12.2020 so it's better for you to get that attested instead of using the domicile certificate of 31.12.2019, to be on the safe side. Getting your Proforma A2 attested is easier so you can get it done easily.

The A1 Certificate should be signed by any A grade officer as for the A2 certificate you can get it attested by your school authorities.

Hope this helps
