Stem bachelors vs masters (ALL ADVICE WELCOMED)

I‘m going into 3rd yr (junior year) in undergrad in my home country and wanted to see if it would be better to transfer into a STEM Undergrad degree or go for a STEM masters instead, to get a job post grad in the US. Any advice?

(My STEM degree is also not actually sciency, more towards communications and social science. So technically it’s not the most wanted in the job market, but the major is still considered STEM)
