I went through much of the application process and would be happy to answer any questions, you can PM me if you would like. It is quite competitive due to Indian preference. I would suggest applying to both non-IHS and IHS programs. The IHS does not use the match system. A residency with IHS has its pros and cons, I would evaluate what you want to do afterwards, work for the IHS? Hospital pharmacy? PGY2? Alaska is the largest site and is quite small in comparison to most residency sites. IHS has little to offer someone interested in specializing or wanting a dynamic and fulfilling internal medicine/infectious disease/oncology/nephro experience. If you want to work for the PHS on the other hand I would highly recommend applying.
