This are just my suggestions
I think it will be better if you do a master program (look into Barry); you need to pull your GPA
Your DAT is good; however, if you really feel that you can get 27, by all means, do it
You didn't apply early this cycle, and that could have affected your chances
I do not think you will get any pre-dec interviews, because most of the schools you applied have finished giving out pre-dec interviews (maybe except NYU)
However, you could still get post-dec interviews
Any research? volunteer experiences??
Basically do whatever you can do make you stand out
I have around 3.3 GPA, 22 DAT and got 3 interviews
It seems regardless what nationality you are
3.3GPA / 22 DAT would get you 3-4 interviews this year (i checked predents)
All I can say is good luck, I really wish you the best
Don't ever give up, just keep pushing it, you will get in
