My suggestion for R1z is that she should lodged the appeal on her husband's behalf inside the UK as she is telling that they had given stupid reasons for refusal so they can give more stupid reasons for delaying or refusing again or misplacing the appeal form or applications. Its safe to lodged an appeal directly with AIT.
I would cerainly not recommend she does above.
Instead she should send the appeal formback to Abu Dhabi or London(whoever dealt/refused it).
The reason why I would do this is to save her self some time.
What happnes is when you lodge your appeal here in the UK with AIT in Leicester, is that they send all your documents back to the Entry Clerance Manager at the place where she applied and was refused.
AIT send this bypost and can take up to 6 WEEKS.
Upon receipt of the appeal the ECM will review the earlier decision in view of what you have said in your appeal notice and and any new documents that you have attached.
If he decides he is satisfied now,he will authorise the issue of visa without the appeal going any further.
If on the other hand he is still not satisfied, he will stick to teh original decision. If he does that , then he will inform AIT in writting.
The AIT will then start to find a date for your hearing. However this date can take up to 20 weeks ( this is time given to the ECO to get his bundle of papers ready for the hearing)
Now if you send it direct to the BHC post abroad,you will save the 6 weeks that it takes for AIT to get the papers to the BHC. The ECM will be able to make the deciosn a bit earlier in view of this.
Remember the only person who can change the original decsion initially is teh ECM not anybody at AIT.
Infact AIT cant change any decison till the day of the hearing when the Adjudicator of the hearing will make the final deciosn in either parties favour.
The only time I would recommend that you send your appeal papers to AIT is when you feel you dont have enough time to get them to post abroad witin 28 days.
Furthermore your advise to Riz is to appeal, its easy saying that, but appealing is not always the best soloution all times. Sometimes it is advisable to reapply and make sure you dont make the same mistakes.
Only appeal if you can disprove the reasons why you were refused at your appeal hearing.
I think it all depends what Riz was refused for. I know she has stated what she "assumed" she was refused for, but its the actual wording of the refusal that is important, because from that you can tell the real reasons why she was refused.
Hope this advice is useful to you.
