Still Waiting

We are still waiting on our I-171H.  Our Social Worker has emailed the Memphis office and we were told that I will have correct two pieces of information.  They also said that our homestudy did not state that our house meets the state requirements for adoption.  Our homestudy social worker has to write an addendum to our homestudy and send it.  This will be the third overnighting fee to USCIS.  We overnighted our homestudy right after it was completed and then we found out that it was sent to the wrong office.  They claimed they sent it to the correct location, however the Memphis office never saw it.  Sooo...we overnighted another copy of the homestudy to the Memphis office only to find out now that we will have to overnight the addendum!! UGH!!  I expected to possibly have to correct information for my application, because another family in my church had to do the same thing.  I did not fill in the blank that I have 0 previous marriages.  I blame the set up of the application.  The other correction I am not sure what to do, hopefully my social worker will be able to tell me what to change. 
I have been obsessively reading blogs for the last several months.  I love the blogs that have the timelines for their adoptions.  However, now I have read a couple new blogs that have their submission date for this dossier as far off as October!! They sent their dossier to Ukraine in March!  We are sending our dossier in the next week as long as I can get to the State Department to get our Petition to Adoption and a copy other document apostilled.  I am completely distressed, because I was quite certain if we requested a submission date by June that we would have our submission date by October.  However, if the wait is 6 to 7 months out then we won't get to submit until January!!   Is that normal for the submission date to be that far out from the date that you request to submit?  I never noticed that much of a gap in other adoptions I have read.  Do they only take submissions at certain times of the year?  I haven't called my social worker to ask her about this yet, but will do that on Tuesday when they reopen.  I am so discouraged about this as I was quite certain we would get to travel this year.  I keep praying that it will all be in God's timing, but I am soo ready to be done with all of this.
