I think you had it all backwards.
The practical training ought to be done in a 145 MRO and not a 147school.
A 147 is just a training centre that offers you the EASA part 66 modules course and confers you the certificate upon completion of the course.
I'm unsure if there are 145 compliant MROs in the US since they are all under the FAA legislation.
If you want to follow through with B1 license procurment then find an employer and join as a fitter to complete your 2 years practical experience.
If you want to join design organizations...etc then carry on with your degree courses.
But most importantly find an employer to secure your employment then do it on distance studies rather than investing a lot of money on these courses for an ungaranteed industry.
I hope it's all clear now.
Good luck
