You might want to consider obtaining an MCSE in Windows 2000 as part of your "gearing up" process. The CCNA is a pretty common entry-level credential that will be worth more with another current credential as well -- which could be a Windows 2000 MCSE or perhaps a CCNP and one or more Cisco Specialist certifications. If your proclivity is toward network infrastructure, as your interest in Cisco certification suggests -- you might want to consider pursuing the Cisco Qualified Specialist credentials for firewalls, IDS or security. See Cisco's Web site for a complete list of these certifications, which you'll find more career-enhancing than the CCNP.
I am reluctant, however, to suggest certification alone is a pathway to "a high-paid job in the USA in the coming years," however. You must understand that meaningful, significant on-the-job experience is every bit as important as certification and you must work to cement and augment your credentials with relevant exposure to and experience with whatever technologies underpin the certifications you decide to pursue for the best possible results.
Good luck with your further certification adventures. I hope they produce the desired results.
