Which form must an alien fill out to obtain an Admin. Stay?

The form that an alien must fill out to obtain an Administrative Stay is the I-246. This form is specifically designed for individuals who are in removal proceedings and want to request a stay of removal from the Department of Homeland Security (DHS). The I-246 allows the applicant to present their case and request that their deportation be temporarily halted, which can offer them more time to seek other forms of relief or resolve their immigration status.

In contrast, the other forms listed serve different purposes: the I-485 is used to apply for adjustment of status to become a lawful permanent resident, the I-1000 does not pertain to immigration processes relevant to stays, and the I-130 is a petition for an alien relative, which focuses on family reunification rather than directly addressing removal issues. Thus, the I-246 is the appropriate form for seeking an Administrative Stay.
