This is the latest nugget of great information that I got (hope the poster doesn’t mind me sharing here 
)
“If you haven’t visited RIT, I’d recommend trying to schedule a visit/tour via the NTID admissions office (which is where you will apply) but also scheduling the regular RIT tour through RIT admissions. The NTID tour goes over a lot of the supports and services they provide, but tends to show less of the actual campus ….if you’re looking to cross register and not just take one of the NTID programs, you’ll want to take the RIT tour to learn about RITs programs. Also (of course this is always a crapshoot!) our NTID tour guide wasn’t nearly as personable as the one who did the regular RIT tour — THAT kid remains my favorite college tour guide ever, over 2 kids and like 25 schools! If there’s a specific major she’s interested in, you can also reach out to the department and schedule time to talk to someone there – my son wasn’t sure if he wanted comp sci, software engineering, or cybersecurity and after his tour he got to meet with professors from those departments to help him make up his mind.”
