In the US, job openings are likely most plentiful in civil engineering out of all the engineering fields. In contrast, BME is one of the worst (if not the worst) of the engineering disciplines for job availability.
Looking at your extracurriculars, I wouldn’t guess that you have an interest in BME. What is drawing you to do graduate studies in BME?
Are you wanting to return to your home country? Are you hoping to work in the US after graduation? Do you dislike civil engineering? Have you taken the FE exam yet?
