Welcome back. Go to your forms.
All USCIS Biographic Information forms are used in addition to other application forms, whenever biographic information is required. G-325C (Biographic Information) is free to file and is only one page long, so if you think you need this form, it is better to file it rather than risk a delay with your application. USCIS Form G-325C specifically asks for your name, address, previous addresses, previous employers, and current and former spouses. This form specifically asks you to provide the past five years of past addresses and employers. The form is similar to other Biographic Information forms (Forms G-325A, G-325, and G-325B).
