If you are talking about a work visa, there could be different reasons for rejection: company’s quotas, nationality, security, other subjective issues…
nothing is guaranteed here..
but I wouldn’t call it “visa fuss”.. it’s still much easier to get a visa here than in US…
and anyway every country has its own rights/reasons to let any person into the country or not… has nothing to do with your ‘american education and work experience’...
