I have been reading a lot of people who are wondering if they should get the new added vaccine about gonorrhea, before their interview.
The answer is no and yes, depending on your PD.
If your application has been received before August 1st 2016, then NO!
If your application has been received ON or AFTER August 1st 2016, definitely yes, you should go to see your initial civil surgeon in order to complete the additional sheet of the form I693.
Here is what I found on USCIS website : "...If USCIS receives a Form I-693, Report of Medical Examination and Vaccination Record, that is signed on or after August 1, 2016 and the form does not contain the results of the newly-required Gonorrhea Component, then USCIS will issue a Request for Evidence (RFE) instructing that the deficiency be corrected...".
So, if you submitted your BEFORE August 1st 2016, You should not be worried. You are just not concerned. That's it!
God bless you all!
