Kour is a little drowned (pun) with his game and the games he plays in. His character is in the mold, but I'll ask him when he'll be ready to start. Worst case, he joins after we started the IC, which is not a problem, since *spoiler* you will all start individually and then somehow we forge you into a team. But as far as I know, he's not an Ork, but thatt doesn't mean he's not noticeable.. You'll see...
About licenses: yes, if you have weapon licenses, it can be traced to you or your (fake or real) SIN. If you don't, if you carry them and a patrol stops you, there will be a problem. Of course, you can carry only self-defense firearms on you, even licensed automatic/bigger weapons must be kept under lock (meaning at home or trunk of car etc.) You cannot walk the streets with a shotgun on your shoulder even if you have license for it.
As far as I can tell, Nina is not in the Salish military, right now she's a doctor of some sort. So she may not carry anything more then self defense firearms legally.
About medical: you are on the bottom of the hospital food chain, working for a very low payment, so max resident or intern. You can access patient files, you have access to drugs, but everything is counted and on paper. Anything besides that is illegal, just as it is in RL. You have a supervisor to report to.
As I said, Day Job is a negative quality

but you can use it to achieve good things, just don't get caught

And you need a medical license, but you don't have to pay for it, it comes with the job.
