Update
Recieved my wife's surrender certificate today via FEDEX.
Total time was about 5 to 6 weeks, via mail. Another person in this group has about similar timeline.
sunks, thanks. glad u like my id.
This is what I recieved in fedexmail from houston today.
1. Surrender Certificate with consul signature and stamp on it. My wife's old indian passport started with 'Z', by mistake I wrote it as '2'. Houston was kind enough to correct it on my wife's Surrender Certificate.
2. I did not get any payment reciept (which we used to get for PIO fee or passport renewal or visa fee). This time, they wrote $40 on the Surrender Certificate. They sent me one copy. I did not fill the bottom box where it says 'applicants name Mr/Ms/etc' and country of citizenship. I thought this was supposed to be filled by houston. So they filled that part. I am writing all this, because there were few directions on the downloaded form. And it seems each consulate has its own version (for example San Fransisco had a photo requirement for SC, where as houston does NOT ask for photo for SC processing). Hope this helps someone in similar situation.
3. They sent the original cancelled indian passport "Passport Cancelled due Holder Acquired US Citizenship". both on first page and last page.
So thats what we got for $40 bucks. I sent $40 money order.
Here is what I sent with application.
1. Printed two original copies of downloaded Surrender Certificate application. I filled everything except for the bottom box where consul officer signs. I did NOT fill the name of applicant and country of citizenship in the bottom small box on Surr Cert application.
2. Sent $40.00 as fee (my wife acquired in 2006 her US citizenship). 20 for processing and 20 for FEDEX. (After the SC processing done by houston, FEDEX automated called with Tracking number the day before I actually recieved the fedex package. )
3. one photocopy of naturalization certificate. (I did not self attest -as the application doesnt ask for it)
4. US passport first 2 and last 2 pages - one copy (I did not self attest this either)
5. Original old unexpired indian passport (because my wife passport was still good till 2016).
6. I wrote a cover letter. basically something like "Dear Consul officer, we are sending application for SurrCert processing and Indian Passport Cancellation, please process with attached required documentation for your review. thanks blah blah"
I mailed it to Houston address with a attn: RENUNCIATION CELL/PASSPORT CANCELLATION DEPT, <Houston_consulate_address> via priority mail.
thats was it. Hope this helps other folks similar situation.
thanks,
My wife and I will apply for OCI now to houston via mail.
