When the federal government unnecessarily delays or wrongfully denies applications for immigration benefits, you have a right to sue the government in federal court. For example, if you have had an interview for naturalization, you can file suit after 120 days if no decision is made. If the Embassy does not issue your family member their visa, you can sue the government. Also, if the government is delaying your asylum case, federal litigation can be a useful tool to force the government to act in your case.
