Working on My Spring Transfer Application- Have a few basic questions?

Hey guys, I recently started the process of applying to transfer to several schools for the Spring semester. University of Virginia is one of my top choices and I plan to start my essays this week.

I have a couple basic questions and it’d be a huge help if anyone can answer!

Firstly, I am now a rising junior (I will be a junior in spring semester) and Mcintire doesn’t offer an option to transfer to the school in the spring semester. Would I potentially be able to switch to UVA in spring as an economics major (my backup option) with the option to internally transfer into mcIntire for fall (Assuming I can get in)?

Also, on the common app, there is only one essay for spring transfers. This is the question:

“How do your possible career or professional plans relate to your planned course of study? Limit your response to a half page or roughly 250 words.”

Does anyone know if this is the only essay? I couldn’t find any other supplementary writing requirements like a personal statement or another essay. I ask this because the other schools I am applying to have multiple essays, some as long as 650 words.

Thanks so much in advance
