Transferring to CIT

Hi y’all

I’m a current Freshman at CMU MCS. I’ve talked to my advisers in MCS and CIT and am thinking about transferring from MCS (Undeclared, but leaning towards Physics) to CIT, either MechE or ECE. My advisers are both in full support of the transfer. The issue is I’m very torn between which department of engineering to transfer in to.
I would really love to do ECE and a lot of my ECE friends are just beckoning me, but the feasibility of transferring in to ECE is completely dependent on space availability, which is not very reassuring. MechE, on the other hand, will be an easy transfer. Also, my CIT adviser advises against “major hopping,” as it’s generally looked down upon.

So I guess my question is what should I do? Should I apply in to ECE or MechE?

Can you request ECE and if there is no space, then pursue MechE? Let us know how it turns out & I hope you get what you really want!!
