Im sure if it says that your application is complete at the top that it should be fine- but, it doesn't hurt to check up on it. You sound like a strong applicant- just what they want; strong GPA, a few years experience, some volunteer experience and well rounded...
I have also applied to University of Colorado- Denver, Northeastern, and UPenn.
I graduated and got my BSN from the US and then moved overseas to Australia and have been working in a medical ward here for over a year. I've got a lot of volunteer experience overseas and spent a few summers volunteering in Africa. In addition I ran a summer camp for inner-city kids in Baltimore for two years. While I've been working, I've been volunteering for a small non-profit yoga studio that helps fund a Hospital in India.
I don't have direct psychiatric nursing experience- I'm applying to the psych NP route. So if I don't get in this round I am thinking of switching jobs. But, for now I really like the people I work with and am getting good experience. My interests for studying further are a bit unique- I want to focus on adolescent girls and would like to work for a wilderness program for teens with mental health problems- one like http://www.snwp.com/.
My recommendations are strong as well. My GPA isn't as great as I'd like it to be- but, I also don't think that is what would get me rejected.
I've also heard good things about seattleU. I thought about applying to UCSF but, I thought that it was going to be even more expensive for me because of the cost of living in the city. Even though I could see myself moving to san fran one day.
I have heard that it has been easier to get into schools because of the financial crisis. I'm not 100% that is true. But, I have a friend that goes to Hopkins and she said they pretty much accepted anyone and were dying for applicants.
Are you taking out loans? or are your parents helping? or have you saved money? just curious of how to do this big investment. hmm...
