I'm hoping I am not making a bad decision... well, more so a forced decision..I won't be able to be in Frankfurt, Germany for my spouse's interview. The flights are just too expensive at this time. I have tried adjusting dates/times and what not, but the cheapest I can find is still $1300-$1400 (with taxes). I am planning on sending my husband the copies of our paperwork that I was orginally going to bring: The I-130, G-325A, I-864 and the DS-230. I also have another I-864 if a joint sponsor is indeed needed. In addition that that, I am also sending along our photoalbum, plane tickets, greeting cards, phone calls and emails.
I hope that's good enough. Can anyone recommend anything else? I think I have all grounds covered. Of course, I know already to bring the interview invitation, passport and medical exam results. Am I forgetting anything else important that will help our case even though I can't attend his interview?
Thanks.

Best,
Przy
