Final answer:
A machine-readable immigrant visa (MRIV) and the foreign passport are two separate documents with distinct purposes. The MRIV is issued by the U.S. Department of State and serves as proof of legal immigration status in the United States. The foreign passport, on the other hand, is an official travel document issued by a foreign government for international travel.
Step-by-step explanation:
A machine-readable immigrant visa (MRIV) is a document issued by the U.S. Department of State that is placed in a foreign passport. It serves as proof of a foreign national's legal immigration status in the United States. The MRIV contains biometric data and can be scanned by machines for verification.
On the other hand, the foreign passport is the official travel document issued by a foreign government to its citizens. It serves as an identification and allows the holder to travel internationally. It contains personal information of the passport holder, such as name, date of birth, and photograph.
Therefore, although the MRIV is placed in the foreign passport, they are two separate documents with distinct purposes.
