Accreditation abroad for graduate program?

I am considering going to a graduate program in Hong Kong, either in marketing, international business, or human resources (all are masters in science degrees). However, all of the programs are accredited/recognized by foreign companies based in Hong Kong, Canada, and the UK. Does this matter if I plan on going back to the United States to work?

In short, how important is accredation for International Business, Human Resources, and Marketing in the American business sphere?

Thank you!
