这个是官方文件 http://www.uscis.gov/policymanual/HTML/PolicyManual-Volume8-Par Timing of the Submission of the Medical Examination Report The medical examination report may be submitted to USCIS: •Concurrently with the immigration benefit application; or •At any time after filing the immigration benefit application but prior to the adjudication of that application; if not filed concurrently with the immigration benefit application, USCIS encourages applicants to wait until USCIS requests the medical examination report before submitting it.

Submit Form I-693 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). Submit Form I-693 in person, at an interview in a USCIS field office (if an interview is required). 只贴事实,不做建议。
