Definitely complete that ASAP, it can take some time for your background check to come in and to get your bloodwork/titers done. However, don't freak out if you don't have it completed by orientation because they actually go over all the clinical clearance stuff at orientation lol I started the process about 3 weeks before orientation and had everything set by orientation, but they were like "if you haven't started this process, get on it RIGHT NOW" and I was like who in the Type B personality hasn't started this?!?!?! Their presentation was very organized and thorough. So if you have any questions, they will be answered. But don't wait, because they will be waiting on you to hand in everything before making the clinical groups and everyone wants their clinical group assignments ASAP. It sounds like they kind of chase you down if they haven't gotten anything from you too. So as long as you've submitted everything you could and are just waiting to hear back on results, don't worry too much about it.
