So ... Virginia is, in practical terms, just a piece of Maryland on the other side of the river? Do I need to keep my (hopefully temporary) MD restrictions in mind in VA?
Others here will describe encounters regarding MD restrictions while carrying out of state. I will say that this is the only time I have ever heard of such an issue. Personally I can't see how another state can enforce MD restrictions but IANAL and YMMV.
VA also issues non resident permits, you can find all the info on the VA State Police website. Your 16 hour MD training fulfills their training requirement.
I have a VA NR permit and it is set to expire in May. I just received the docs to renew but they are currently running 3-5 months to issue. I will continue to carry in VA on my MD permit if I don't get my new NR VA permit before it expires.
