No invite for F2F yet either. Read a few posts on RST American FB page a couple days ago where the applicants waited a little over 2 weeks so I think we’re still in the realm of normal. Hope the best for you as well!
Same timeline for me as well. It’s been about 15 days since I received and completed request for more info which was about a week after submitting video interview. Hoping F2F request shows up soon, not panicking yet!
