If you have been living in the United States after entering or staying illegally, but since become eligible to immigrate on a family-based green card, you might have realized that you face a major legal barrier: When the date comes for your green card interview, you'll need to leave the U.S. for a U.S. consulate in your home country (because your illegal entry probably makes you ineligible to use the U.S.-based "adjustment of status" application procedure). But the officer you meet at the U.S. consulate might deny your immigrant visa and block your return based on your past unlawful time spent in the United States. The legal term for this is "unlawful presence" or ULP.
One solution to this trap is what's called a "provisional waiver" (or "stateside waiver") of the unlawful presence ground of inadmissibility (as found in 8 C.F.R. § 212.7). Here, we'll discuss:
(For a full discussion of the underlying problem for people who have lived in the United States without immigration papers or permission, see Consequences of Unlawful Presence in the U.S.—3- and 10-Year Time Bars.)
The possibility of requesting a waiver of unlawful presence existed before the "provisional waiver" was created. But it couldn't be requested ahead of time, for those people needing to visit a U.S. consulate as part of their application process. By applying for a provisional waiver, you can get a "yes" or "no" answer from U.S. Citizenship and Immigration Services (USCIS) before departing the United States, instead of at or after the visa interview.
With a "yes" answer, you can leave the United States feeling fairly comfortable that the consular officer will approve the immigrant visa at your interview and allow you to return to the United States with an immigrant visa, as a lawful permanent resident. (The consular officer can still override the USCIS decision and deny the waiver, or require you to apply for a different waiver if they find an additional ground of inadmissibility in your case, but such occurrences are relatively rare.)
If the answer from USCIS regarding your waiver request is "no," you will at least find this news out while still in the United States, not trapped outside facing a bar of 3 or 10 years on your return. You might even be able to reapply for the waiver. Or, you could take a chance and leave the United States for your consular interview and present the waiver application there. Speak to an attorney before taking this risk.
When the provisional waiver first became available in 2013, applicants had to be immediate relatives of U.S. citizens—that is, a spouse, parent, or unmarried child under age 21. In 2016, however, the waiver was greatly expanded. Now, anyone who is eligible for an immigrant visa (whether based on family, employment, the diversity visa lottery, or a special immigration classification) may apply for it.
The other eligibility requirements are that the applicant be:
The agency in charge of deciding on provisional waiver applications is USCIS even if the applicant is in removal (deportation) proceedings before an immigration judge (who is part of the Department of Justice). Only applicants whose removal proceedings have been administratively closed and have not been re-calendared, however, will be eligible to apply. After USCIS approves the waiver, such applicants will need to obtain termination or dismissal of their cases by the immigration court before leaving the United States for their consular interview.

And because of the complexities of preparing such an application, consider hiring an experienced immigration attorney to help analyze your eligibility, prepare the documentation showing that plus the extreme hardship your relatives would experience, and so on.
