Concurrent filing of Form I-485, Application to Register Permanent Residence or Adjust Status, is when an adjustment of status application (Form I-485) is filed before the approval of the underlying immigrant visa petition. We will consider the immigrant visa petition and the Form I-485 concurrently filed when you file them at the same time and mail them together with all the required filing fees and supporting documentation to the same filing location. We also will consider them concurrently filed if you file the Form I-485 after the immigrant visa petition but while the immigrant visa petition remains pending.
