Leave your nonsense aside and support your arguments with evidences or else zip it here.
Back to the issue, it might be so in your case and of course you had to present the CENOMAR to support that you had no other marriage, as you were waiting for spousal visa. Here, we may assume and it makes sense to argue one possible reason why the embassy needed the certificate is to just proof that you are not attempting to escape from any other marriage. However, your scenario becomes irrelevant to cases like F2B and F11, where the benificiaries are required to remain unmarried/single throughout their process, not only in their country, but also any where they lived. Not being so jeopardises their visa cases. For such cases, there is no other way or documentation the benificiaries can proof their no-marriage status except by presenting CENOMAR. I have challenged the participants of this discussion including you to suggest any other way or option to reslove such issues, non of you suggested one. Infact there is no other explanation why these days quite a number of US and even other embassies request this document except to ascertain that the applicant isn't married or single.
I had my cousin and brother who had gone through similar scenario when they appeared for their family preference immigrant visa. They were stuck and required to present a CENOMAR during their interview at the embassies. And after presenting those documents, the embassy granted them their visa. If this certificate had no relevance to proof the no-marriage of the applicant of F2B and F11, then why did the embassies have to request it???
