Texas is home to tens of thousands of immigrants. Each person's journey to the United States is unique although many people's experiences share certain issues in common. For instance, a great number of people enter the U.S. through the family immigration system.
Under federal law, U.S. citizens are allowed to petition for green cards for certain relatives. This includes parents. Typically, U.S. citizens that are over 21 are eligible to pursue a green card for parents who are from another country.
