Where to File
After completing your the medical examination, the civil surgeon must give you, the applicant, the completed Form I-693 in a sealed envelope. Do not accept it if it is not in a sealed envelope. We will return the form to you if it is not in a sealed envelope, or if the envelope has been opened or altered.
You (not the civil surgeon) must submit your Form I-693 to USCIS. If you are applying for adjustment of status, you may submit Form I-693:
By mail with your Form I-485, Application to Register for Permanent Residence or Adjust Status, to the location specified for your Form I-485 (see Direct Filing Addresses for Form I-485
By mail after filing your Form I-485 to the location specified in your most recent communication with USCIS (for example, a Request for Evidence letter from USCIS).
In person at an interview in a USCIS field office (if an interview is required).
你現在要做的是第二個選項"By mail after filing your Form I-485"，所以要寄到USCIS最近一次連絡你的地址。
