International students returning to the US after winter break must carry proper documentation to avoid secondary inspection at ports of entry. Key documents include a valid passport, F-1 visa, and Form I-20 with a current travel signature. Supporting documents such as financial proof, enrollment verification, SEVIS fee receipt, and OPT-related paperwork are recommended. Secondary inspection may occur if documents are missing or SEVIS records are updated. Recent policy changes affect visa applicants and social media requirements.
