I'd second the recommendation made in post # 6 , that you fill out a ORDER FORM on Travisa website based on what you need, and based on when you naturalized.
- Since you are attempting to combine the request for Renunciation + OCI together , the fees to Travisa is $12.00 along with the Consulate fees. I'm sure the fees for Renunciation is
NOT included in the OCI fees, as you indicate and are 2 seperate charges.
However, combining these 2 requests together will entail more sets of documentation copies in your packet, which the Travisa documentation will list. (I personally have not used this route to combine Renunciation with OCI, so cannot speak on the no of sets of documents. I applied Renunciation first, and just now send in my OCI pkt.)
Once you fill out the Order form for OCI - Adult , and answer all questions (including the checkbox that you are applying for Renunciation also in the same Order), it will let you know the total fees. I do recollect that the Charges for Renunciation to be bumped up to $178.00 (from $175.00, as it went a $3.00 increase -- so PLS RECHECK before you get the Money order/Cashier check made. Going with what your Order form indicates is be a better way).
PLUS ensure, that all documentation is structured exactly in the same order it is listed on the Order form when you do decide to turn in the Pkt to Travisa.
Your question on photos was answered multiple times before by multiple people. Many of us have used the Standard photos applicable for US passports (2*2/white background), and that is also listed as the requirement to the Photo specification link for the OCI page. Will that work for everyone - is a tricky one. My case is just now in the pipeline...
