Some USCIS immigration forms request that you fill out and file G-325A (Biographic Information) in addition to the form appropriate for your request. USCIS Form G-325A allows you to supply additional biographic information — which can include information about past residences, your education, your past work experience, your family, and other facts of your life. The USCIS can then use this information to help evaluate your eligibility for your original petition or application. G-325A is a fillable form, which means that you can complete it on your computer with a free software called Adobe Reader. If you can, using this software makes it easier to include all your information and to keep your form tidy and organized.
