I would like to know which method can get my passport faster.

On line application could be found here https://pptform.state.gov/
However, I heard you can prepare your pre-printed and filled form to your Oath Ceremony.
Pass that form immediately after your ceremony to the assistant on site.
Which way is faster? Thank you for your sharing.

I would suspect doing it at the oath ceremony will be quickest, after that ans DOS will need evidence of US Citizenship (Copy of naturalization Cert) which can take some time to get from USCIS.

I understood you received the Naturalisation certificate at the Oath ceremony??

In terms of time I do no think it makes any difference since they process first come first serve. However the online link only allows you to fill and print the form. To file you actually have to go to an acceptance facilty, provide photos, etc. In light of that I would think filling at the oath ceremony would be more convenient. It would also be faster in the sense that you do not then have to go someplace again to submit your forms, but not faster in the sense that your application gets a priority.

Once you have your Certificate of Citizenship in hand, go online here and it will be the fastest from my research. I used them today and they said my passport should be here by tomorrow evening! Keeping my fingers crossed but it was recommended by the clerk of my local court where we apply for passports so everything should be good. In my case I needed to renew a passport but they should be able to do regular applications as well I think.
