Thanks so much for all the answers!

Still a little confused about one of my questions:

does my fiance (beneficiary) submit a set of copies of her originals at her interview, plus having her complete set of originals with her to show the interviewer in Manila?

I'm in Texas and my fiance is in the Philippines.  I understand that I need to send exact photocopies of unaltered, original documents, and that USCIS may require me to submit original documents to USCIS at a later date.  Here's my questions: 

1)  Should I submit copies of both my (petitioner) and my fiance's (beneficiary's) documents with the I-129F, or just copies of my documents?

2)  If only my documents, does she submit a set of copies of her originals at her interview, plus having her complete set of originals with her to show the interviewer in Manila?

3)  Will USCIS ask me to submit originals later (if needed) for myself (petitioner) , or can I give the set of my original documents to my fiance' (whom I'll be visiting again in 1 month), to present at her interview?

4)  Do I need to have a complete set of copies of her documents that she will take to her interview before I file my I-129F?

I haven't seen anything on this, so I hope I'm not asking a duplicate question.

Thanks so very much.  Tom (US) and Josephine (Philippines)
