What application do they mean? Confused

Thanks to Ksand24 for helping me with a lot of this.
Just wondering what Application is being spoken of here
If anyone knows for sure
I would have already submitted it online, correct?
Hmmm. . .
I am concerned because I will not have a car or printer in the US and would like to prepare before I leave for the US to apply
Part one of the app was 16 pages. . .
Maybe I will print it all out and take it with me as a precaution. . .
Has anyone else done that?
Thank you!

Post your application
Once your appointment confirmation letter is stamped at the ASC, you will have 5 days to post this, your application form, current passport, UPS return shipping label, and any supporting documents (if you haven’t uploaded them online) to:VFS Services USA Inc.

Please can you post all your questions about your application in one thread only. You already have a topic set up for your visa questions, so please use that one for all your posts.

By doing that, it makes it easier for us to help you (as all your information will be in one place on the same page) and it stops the forum from being clogged with by multiple topics from the same person.

:

By ‘application’, it generally means the first page of the application form, and we already discussed whether or not you need to print it in your other thread:
https://talk.uk-yankee.com/index.php?topic=98811.msg1306279#msg1306279

I’ve also just answered your question In that thread about what else needs printing too:
https://talk.uk-yankee.com/index.php?topic=98811.msg1306284#msg1306284

You won’t be able to print any of these things before you go back to the US, as they can only be done AFTER you have submitted the online application.

Thank you so much
