Start with the CDS and look at how many apply and the acceptance rate.
Then go to the websites and look at the transfer application requirements, and speak with a transfer advisor.
U Mich has transfer tuesdays, where one can tour and meet with a transfer advisor to go over the courses the student has taken, and see which ones might transfer over. Don’t know if UVA has the same, but look on the website. Of course, no schools are having tours or in-person meetings at the moment.
Unless the student attends a school that has an articulation agreement with the target transfer school the student may lose credits and not be able to graduate in 4 years. There will also be little, if any, financial aid for OOS transfers at most publics.
If you give more specifics posters will be able to better help you. For example…Are you at a CC now? A 4 year college? How many credits do you have? GPA? Major? Would you be applying for FA?
