I am currently doing BBA in marketing and planning to pursue MBA abroad. Can I take up HR instead of marketing in it?

Hi Om, Yes, you can opt for HR instead of Marketing, but you'll be able to get a good job only if you have expertise in it. So, prepare well. All the best.

Yes, obviously, my friend, you can. If you are having interest in marketing, you must choose it. Develop your skills. Best of luck!

Yes, why not. You must demonstrate your interest and career plans clearly, everything depends on your essay. This is why MBA programs abroad requires or prefers applicants with work experience.
