Frequently asked questions

It depends on your situation: family, employment, asylum, or other categories. In a consultation we review your background and explain the possible paths and their requirements, without promising an outcome.

In many cases, yes: spouses, children, and parents of citizens or residents may qualify for family petitions. Each case has different timelines and forms (for example, I-130).

Defenses such as cancellation of removal, asylum, or adjustment of status exist depending on the case. Deadlines are strict, so it is best to seek legal guidance as soon as possible.

It varies by case type and USCIS fees. At the first consultation we give you a written estimate of fees and government costs before starting.

From months to several years depending on the category and the processing office. We share current estimated timelines and how to track your case.
