overstaying a country

What happens in Europe stays in Europe. European trip violations have nothing to do with US immigration law. A US consular officer would not be interested in the happenings in Europe and in a marriage case would only be interested in the bona fides of the marriage and whether that person was excludable from the US for any of a variety of reasons including crimes, addictions, or memberships in questionable organizations.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.

Overstaying a visa to another country will not affect the US consulates decision to issue a visa.  They won't know about the overstay since that information is only privy to the country in question, assuming that country even tracks it.
