Call your insurance to see if they cover:

  • Serum RPR

  • Adecel, varivax and MMR-II vaccine (which you may need)

If the insurance company asks you which doctor is ordering these tests, “Dr. Leung, NPI = 144-631-8711” If they say yes, we offer these blood tests at this clinic. You may choose to have your blood drawn here at the clinic. If they say no, you may want to go to your PCP, as they also provide these blood tests. Decide if you wish to do your vaccines at the clinic or at CVS. More information is below.

What to Bring to the Exam


On the day of the visit bring with you:

  • Payment (money order or cash). No personal check or credit card.
  • Original of the documents you sumbitted for verification purposes

What it takes to complete the Form I-693


  • Physical examination and interview
  • Up to date vaccinations
    • We will review your immunization records and based on your age, medical history, and other risk factors. We will tell you the specific vaccine(s) you will need to fulfill the i693 application, per USCIS and CDC guidelines. The requirements can be confusing to applicants as it depends on many factors (such as other medical conditions). It is understandable that applicants may want to obtain required vaccines prior to their initial civil surgeon visit but in our experience, unless one is very familiar with the CDC guidelines and constantly checks for updates, it is not an easy task for non-medical, or even medical professionals who are not familiar with the i693 application requirements. In addition, it will not save you time, as vaccines can usually be administered on the same day as the medical examination.
    • The applicant has the option to receive the required vaccine(s) at his/her own PCP's office, the local pharmacy such as CVS or Walgreens, or at our clinic. Many pharmacies have contracts with your insurance and may be able to tell you real-time whether certain vaccines are covered under your health plan.
  • Serum QuantiFERON®-TB Gold (for applicants 2 or older, with some exceptions)
  • Serum RPR (for applicants 15 or older, with some exceptions)
  • Urine Neisseria gonorrhoeae RNA, TMA (for applicants 15 or older, with some exceptions)
    • The above three tests are the most common lab work required for the i693 application, but there are exceptions depending on your unique situation. Based on our assessment during your initial visit, we will tell you exactly what lab work you will need to fulfill the application. Applicants have the option to obtain these required lab samples at our clinic, local Quest Diagnostics, PCP office, or your preferred local laboratory. If you obtain your lab work at our clinic or at Quest Diagnostic, results will be sent to us automatically. If you choose to obtain lab work elsewhere (such as PCP office or other local lab), you will be responsible for sending our office the lab results.
    • The immigration medical exam is intended to be a snapshot of the applicant’s medical status. While there is no defined period of time during which a chest X-ray or lab work is valid,we STRONGLY advise that you obtain lab work and other i693 related studies AFTER your first visit with us. Lab results usually become available in 2-4 days.
