Well I'm back safey from my trip. I apologise for not responding earlier to all the comments, but I was in China. I guess I caused a small storm!
I'll start with an apology. I honestly didn't mean to be rude by calling other posters "alarmists" or anything else I said (but I see that it can be taken that way). I was interested in an actual debate about if we're all just getting too stressed about this. It has been very stressful for me, and I'm apt to get over worried about it I think.
As cherr1980 said I probably was just looking to hear that it was OK for me to go on my trip - and lucky me I got that advice from a lawyer a the university international student and scolar office. So I went, albeit with many misgivings based on concern about what I was doing from postings here. Perhaps I was wasting the forum's time since I was looking for this one answer, but on the other hand you're all posting voluntarily right...? Also I appreciate eddie_d's comments about the nature of message boards being that you only hear the problems. I'm not a usual message board frequenter, so I guess I missed that point a bit.
Silly really since I ran across this in the first place once I started to get stressed about whether I would get my AP in time for my trip (it arrived with a week to
spare) and Googled the question!
As it turns out everything seems to have worked out fine for us. We got a letter while away asking for appearance on August 9th next week. So I guess I'm amazingly lucky on this. I hope we can use this to get back to the title of the post - is there anyone else out there with actual experience with rescheduling? Do we know any real or anecdotal evidence of people who suffered terrible problems because they rescheduled? All I could find on the internet was a woman who rescheduled twice because her husband was posted overseas in the US military. In her case it extended the process by several months - which was what I expected for the outcome of my rescheduling. I have been amazed on both occasions how quickly the interview was rescheduled for me (FYI it's Boston DO).
I would also like to debate anjafromsweden's comment that we have no rights to feel entitled. I do feel entitled to live with my husband (either here or in my home country of the UK). I hope that USCIS feels that it is their job to prove people are applying fraudulently and not the other way around (innocent unless proven guilty), but maybe I'm being naive. They have to be careful of course... I understand that, but if you're really married legitimately I don't see the problem.
Finally I would like to say that despite my positive experience, it really does seem like the sensible move to avoid rescheduling as much as possible as per everyone's advice. Until further experiences come a long I have to assume I've been incredibly lucky, and I have to say I did worry a bit while away about the outcome, so for peace of mind coming back early might have been better anyway. As charchamps says we all make choices in life, sometimes good, sometimes bad. I'll add that we have to accept the outcome, and in my case it has turned out OK so far.
I'll post again after the interview to let you know if they give us a hard time about the rescheduling.
FYI the trip to China was great.
My first time in Asia.
