First thing you need to do is ask your concerned University about what kind of evaluation they accept. For example, The type of evaluation that university accept varies from University to University. So, first thing you need to do is ask your university, what kind of evaluation report they prefer, since there are my credit evaluator in US.
Once you get that information, contact the evaluator directly and figure out what they would need for specific kind of evaluation as stated by university. Gladly, they will say what you are going to need.
As far as i know, they don't want your sealed transcript from TU. You can go to international office at your present school and then attest it and send them through and it will be sufficient. Any more questions, gladly reply you back
