I can totally relate to you. I applied to 10 schools for their Ph.D. in Neuroscience, and I am afraid that I will end this application with zero offers.
I am an international student, but I have been in the US for seven years and obtained two masters (electrical engineering and biomedical engineering) from US schools. I have 2 first-author journal publications (one more submitted), 1 book chapter, 1 US patent, 5 conference posters/abstract, 20 months of full-time (40 hours/week) research experience. Taught 79 undergrad students for the lab session. Mentored six undergrad students, with five of them went into grad programs globally. I have 6 months of clinical study/data collection experience too.
None of the above gets me an interview, at all.
And this how I deal with it. Perhaps it can help you a little bit as well.
First of all, don't jump to the conclusion that it has anything to do with your race, or nationality, or any other social/physical factors. Because you cannot change those facts. Believing that those social factors are the reason that got you rejected will only make you feel hopeless, angry, and give up self-improvement.
Focus on things you can change: Learn how to better organize your application packages for workshops, select a better scholarship program that fits you (or you fit their vision), get involved in lab research and start publishing, etc. I am not selling you the "positivity" BS, but self-improvement is our only hope.
Second, if you have tried really hard and give everything you got but still failed, it's ok. I am a big believer in "If you have to fail, fail early and fail hard." After the first three days of feeling pissed and personally offended for being rejected, I started to figure out a thing: If all 10 schools don't think I have what it takes to be a successful neuroscientist, then it is very likely they are right. They probably are doing me a favor, saving me from a bigger failure many years later. Failure is not the worst. Failing after 10 or 20 years is the worst.
The world is just fine before I am here, and it will be fine after I am gone. I don't matter that much to the world.
The only thing that matters to me is being happy and making people around me happy.
Good luck, my friend. Maybe good luck is the only thing you don't have yet.
