Your GPA is fine, so no need to worry about that. The main "flags" that pop up to me are, as you've mentioned, your GRE score and research experience. Additionally, being an international applicant can be a good thing for some schools, but a hindrance at others. The fact that you only applied to two programs was also a big red flag, as it significantly decreased your chances of gaining an interview from the outset. What I would suggest:

Just to clarify, your GRE scores aren't too bad. According to the old scale a 155V (530) 155Q (700) converts to about a 1230

Perhaps try to get a year or two worth of research experience as a Research Associate. I don't imagine it to make a difference where you get your research experience as long as the research team you work with is relatively active in research dissemination (peer-reviewed publications, presentations, posters, workshops, etc). And DEFINITELY apply to more schools. You should generally target about ten, give or take.
The work you've done until now is quite impressive! My thought is with some extra added effort, you will certainly gain admission. You could apply next year. I mean, you were very close to gaining admission; the fact that you were interviewed and subsequently wait listed at one of the two schools is a good sign. Whether you apply next year or hold off is up to you. That said, more research experience can only work in your favor, and may help you better understand what you want in a program.
