Hello TIyasha

Just go through this list which clearly sates the documents compulsory for JAM counselling.

10th Certificate

12th Mark Sheet

Qualifying Degree

If completed the degree: Marksheet of all semester/years

If in final year: Marksheet till last year or semester

Nationality Certificate for General category:

Birth Certificate

Voter ID

First page of passport or School/College Transfer Certificate (CTC)

Nationality Certificate issued by the authorized government agency

As you can see that Transfer Certificate is only needed for Nationality and instead of this you can show any other Proof too. So, no need to worry.
