Your ability to return depends heavily on the type of status or visa you currently hold in the U.S. If you’re on a nonimmigrant visa, you must make sure it will still be valid when you come back. Otherwise, you may need to apply for a new visa at a U.S. consulate in Germany before returning.

If you have any pending immigration applications or plans to file soon, long travel outside the U.S. can complicate or cancel certain filings. Adjustment of status cases, for example, typically require advance parole to re-enter legally. It’s important to check how international travel interacts with your specific immigration plans.

Before committing to the program, consider speaking with an immigration attorney to review your current status, travel risks, and re-entry requirements. They can help you determine whether you need additional documents such as advance parole, a renewed visa, or proof of ongoing ties to the U.S. Preparing ahead of time ensures you can travel without jeopardizing your stay.
