What type of document is essential for a pending adjustment of status application?

The essential document for a pending adjustment of status application is a current mortgage or rental contract. This document serves as proof of residence, which is important in the context of establishing eligibility for adjustment of status. Immigration authorities need to know where an applicant resides and to confirm that they are maintaining a stable living situation in the United States.

A mortgage or rental contract provides clear evidence of an applicant's address, which can impact the decision-making process regarding their application. It also helps affirm the applicant's ties to the community, an important factor when evaluating their intention to remain in the U.S.

While documents such as a tax return, a letter of employment, or a birth certificate might be relevant for various aspects of the application process, they do not specifically address the requirement of proving current residency in the same direct manner as a mortgage or rental contract.
