I am so sorry about what our friend went through.I do respect those Visas Officers, especially that they are a lot things they know and see that we do not see (behind closed doors). However this way that man was treated is not fair.even if he might not be eligible.I am so sad that some Visas officers might be held by personal emotions than looking on facts. a Visas officer is like a judge,thus he/shoud not let be hold by personal emotions.
back on facts that she hold your documents here is what I know about their process/policies:
I quote ''Officers may keep contentious or questionable documents on file during processing. If officers rely
on a document to refuse an application, they will keep it on file, microfilm or microfiche after
finalization.'' end of quote.
If you feel that your relation is real the appeal as some colleagues suggested you.and if you win the Visas officer won't be able to deny you.
Personally I saw in my notes a visas officer saying that there is so much erase on my marriage certificate which was not true because the erase was just on my Family name since it was misspelled and Icouldnt accept to take it that way.byt that correction resulted in ''a lot of erase''. however the VO are human as we all make mistake.so take hurt if you guys you are in real love you will make your way.we can't put aside their judging too, since nowadays they are a lot of spouses that gives a Bye bye to their sponsors a few months after they landed.but i your case it is not the case since she misstreated both the sponsor and he applicant.it was just personnal emmotions.
keep heart. youw ill make it and you are not alone. I don't know much on appealing process but for sure here you will get people who crossed same storm and managed to arrive safely.all the best!
