What after MBA in HR ?

After an MBA in HR I do hope you plan to enter the work force.

If you plan on teaching, you should really be looking into social, community, or cross-cultural psychology doctoral programs instead.

There is no such MBA. Universities don't grant MBA in HR, or MBA in finance, or MBA in marketing. They grant the degree Master in Business Administration, or they offer the MS in finance, MS in marketing, etc. The MBA is a general degree preparing students for management positions in any level of a business, up to CEO. MBA students study accounting, finance, marketing, management, statistics, economics, strategy, policy, and other courses. Many MBA programs offer concentrations in these and many other fields, but that amounts to only 2-3 courses in your chosen field in the second year of study. Regardless of concentration, you still earn just the MBA.

After the MBA you get a job.

Consult the Official MBA Guide. It's a comprehensive free public service with more than 2,000 MBA programs listed worldwide. It allows you to search for programs by location (US, Europe, Far East, etc.), by concentration (finance, marketing, aviation management, health management, accounting, etc.), by type of program (full-time, distance learning, part-time, executive, and accelerated), and by listing your own criteria and preferences to get a list of universities that satisfy your needs. Schools report their accreditation status, tuition cost, number of students, class sizes, program length, and a lot of other data. Schools provide data on entrance requirements, program costs, program characteristics, joint degrees, and much more. You can use the Guide to contact schools of your choice, examine their data, visit their web site, and send them pre applications. You can see lists of top 40 schools ranked by starting salaries of graduates, GMAT scores, and other criteria.
