I plan to apply in the United States.
* You need to do your homework on physics graduate programs. In the US, they are different from those in many other countries, in which you complete your Bachelor's, apply for a terminal/standalone Master's, and (after you complete your Master's) then apply for a PhD if you choose to. In the US, you typically complete your Bachelor's, and then apply for a PhD if you choose to. The US PhD programs meld the Master's and PhD programs offerred in other countries. But the key point is that many US universities (especially the ones with the top physics programs) don't even offer a terminal/standalone Master's in Physics program for you to apply to. There are exceptions, though, if you search hard enough.
* There is also the issue of funding. In the US, if you are admitted to a PhD Physics program by a university that really wants you, you will be fully funded: tuition waiver and a stipend to cover basic living expenses. Funding is initially provided by teaching assistantships (most common), research assistantships (in some universities these are not available until you pass your quals; but some universities do provide them for new students), fellowships (for top students they really, really want), scholarships, or some combination of the above. Once you start research, you are typically (exceptions apply) supported by a research assistantship.
I don't know the state of current funding, particularly for foreign students (a lot of turmoil under current federal government policies); perhaps others can chime in on that.
If you do find a terminal/standalone terminal Master's, you will likely have to pay your own way (perhaps there are exceptions if you search hard enough; I don't know).
* So we loop back to the questions posted in Reply #2: Why do you want to get a Master's and what do you plan to do afterwards? Added to those, do you have the means to pay your own way? You should address those issues first. There is a wide range of universities in the US, ranging from mediocre to top-notch. The question of whether you can get admitted will depend on how good a program you want (or will settle for) and whether you can pay your own way.
