Hello @Damiores,
Yes, all well. I research and asked the London Embassy, most of the info is on the embassy appointment site, but see below for detailed steps I followed
These steps may only work after you get an original Interview date from the NVC, which was my situation, I think this is because once NVC sets an appointment date, the case gets transferred to the embassy and they now handle the case.
1. You need to register/create your account onto the Embassy site using the info on your original appointment interview, add you and your partner on the list of applicants/derivatives
2. Then you'll see the original appointment there, and you'll need to cancel it.
3. Then I contacted the embassy using a form on the website and let them.know what was going on and they told to reply to this email LondonInfoUnit@state.gov, once you have obtained your child's 1) birth certificate with parental information and 2) passport.
Once you send them these 2 docs via email, they will add our child to your case, remember to send them your case number LNDxxxxxxx.
4. Once they confirm your child has been added, they will also let you know to make sure you complete a DS-260 online and a fee will be payable for him/her on the day of the interview. All applicants, regardless of age, are required to complete a medical examination performed by an Embassy approved physician in London prior to their visa interview.
You fill out the DS 260 online, just like you did your partner and yours, you'll see that your child.now appears as a derivative as pending
5. Once you complete the DS 260 (much simpler for a newborn as they dont have any history). Submit it. And once that is done, you'll be able to print his/hers DS 260 confirmation page which you will need along yours and your partner on the day of the visa interview.
6. Log in back to the embassy site (step 1) and you can now add your newborn as a derivative using the info on the recently printed DS 260 confirmation page of your child.
7. Once all of you are added on the embassy appointment site, you'll then be able to select/schedule a new date there.
NOTE: The site and information says you can only set a new date after the original date has passed.
The birth certificate should be straight forward and you can get acopy the same.day on your appointment when you register the birth
I applied for his British passport online and took 8 days in total from submission, sent docs the following day, but you can use any passport you get for the child.
You need passport for both medical and embassy appointment (you need birth certificate to get a passport)..
Also, for the interview they require originals of all civil docs (your child will only have birth certificate and passport), you and partner will also need police certificates, birth certificates and marriage certificate (all originals).
Extra info for Medical: we did the medical on the 8th of Dec, child was 5 weeks old, and took his passport (origonal) birth certificate (copy) and you have to fill a medical questionnaire and Not sure if you need to bring a summary care print out for the baby (we did) he also has medical examen, but much much simpler.
They will not sent results of the medical to the embassy, until your baby is vaccinated for Hep B and Dtap) is less than 8 weeks old, in the UK the first vaccine happens at 8 weeks which is a 6 in 1 that include the 2 mentioned before plus some other (1st dose). We have a our child vaccination shedule for end of Dec and all we need to do is send visa medicals proof of the vaccinations via email, which we will request from the surgery/GP on the same day, his vaccines will be given 6 days before interview amd we plan to send proof the same.day he gets his shot.
As long as you leave at leave 5 / 6 days form the moment your child gets his vaccine and.the interview date, then no further delays should happen, you can also choose to have the medicals after your child has been vaccinated, but unsure if they will require other vaccines after 8 weeks of age.
The above seems long, but wanted to make sure you had as much details as possible.
Any questions let me know. but also use the embassy email above, they respond within 2 to 3 days.
Goodspeed and congrats again.
