International travelers unable to enter countries due to name discrepancies in immigration records

Travelers who have previously visited countries under a different name (due to marriage, legal name change, or documentation errors) face potential denial of entry or lengthy immigration delays when their current passport doesn't match historical travel records. Immigration systems flag these discrepancies as security risks, and travelers lack a clear, official process to resolve the mismatch before arrival, forcing them to navigate complex bureaucratic procedures at borders or risk being denied entry entirely.
