Certain criminal convictions, unlawful presence, prior removals, and other grounds can make someone inadmissible to the US, blocking a visa or green card application. Some of those grounds have waivers available, others don't. This screener identifies the most likely inadmissibility ground in your situation and whether a waiver pathway exists.
Filing a visa or green card application without first resolving inadmissibility grounds is one of the most common and costly immigration mistakes. An immigration attorney can review your full record and advise on waiver options before anything is filed.
Inadmissibility means USCIS or a consular officer can legally deny a visa or green card application based on specific grounds listed in the Immigration and Nationality Act. These grounds fall into several categories: health-related, criminal, security-related, prior immigration violations like unlawful presence or prior removal, and others. The exact ground determines whether a waiver exists, which form to use, what standard must be met, and who qualifies as a qualifying relative for hardship-based waivers.
If you're in removal proceedings already and inadmissibility is being used as a basis to remove you, the issue overlaps significantly with relief options covered in our deportation defense screener. For people with a criminal history specifically, inadmissibility often surfaces first when filing a green card application, sometimes years after the underlying offense, making early attorney review before any filing critical.
Unlawful presence in the US triggers time-based bars to reentry after departure. Accumulating more than 180 days but less than 1 year of unlawful presence before departing triggers a 3-year bar. More than 1 year of unlawful presence before departing triggers a 10-year bar. Both grounds have waiver options for qualifying applicants with a US citizen or permanent resident spouse or parent who would suffer extreme hardship. The I-601A provisional unlawful presence waiver allows eligible applicants to apply for the waiver while still in the US, reducing the time spent abroad waiting for consular processing.
Several categories of criminal conviction trigger inadmissibility, with different waiver availability for each. Crimes involving moral turpitude, controlled substance offenses, prostitution-related offenses, and multiple criminal convictions are among the most common grounds. Aggravated felony convictions are the most serious, creating a permanent bar to many forms of relief with very limited waiver options. The specific offense, state of conviction, date, and whether the conviction occurred before or after any prior admission to the US all affect which ground applies.
A prior removal or deportation creates a separate bar to reentry, lasting 10 years for most removals, 20 years for a second removal, and potentially permanent for certain aggravated felony cases. Reentering the US illegally after a removal makes the bar permanent in most circumstances and creates additional criminal exposure. Waivers for prior removal bars are available in some cases but require showing compelling reasons and are not routinely granted.
