Yes, you can travel to Nigeria with your expired Nigerian passport and return to the USA with your valid USA passport. Here are the key points to consider:
Traveling to Nigeria:
As a Nigerian citizen, you can enter Nigeria with an expired Nigerian passport. However, you may need to provide additional proof of your Nigerian citizenship, such as a birth certificate or a government-issued ID.
You can also obtain an Emergency Travel Certificate (ETC) from the Nigerian Embassy or Consulate in the USA. This document allows you to return to Nigeria and is valid for a single trip.
Returning to the USA:
As a dual citizen, you must use your valid USA passport to enter and leave the United States. U.S. law requires all U.S. citizens to enter and depart the country on a valid U.S. passport.
Make sure to confirm with your airline if they accept expired Nigerian passports or ETCs, as airline policies may vary. Safe travels!
