If we are still talking about the Manila embassy, then this isn't true at all, or misleading at best. Its causing a lot of unnecessary panic and fighting in other forums. For many people, its easy to get a certified copy, but in other cases its not and this is causing so much panic.
If it is true, then please provide hard data, proof, and the exact circumstances of the event instead of some authoritative sounding statement without any credentials or facts backing it up.
Here are mine:
1) The Embassy falls under the DOS, as well as the NVC, and there are no rules or requirements for the consulates to REQUIRE ANY original or certified copies from the petitioner. Only the beneficiary is required to have originals for their own civil docs.
2) The USCIS in USA, before it gets to the DOS, is much better equipped to judge the validity of the civil documents, and even they don't require originals except for court documents, and so the DOS doesn't require originals at the NVC or consulate level.
3) The petitioner does not need to give the beneficiary any originals for their interview, This includes divorce certificates, court documents, I-134, tax returns, and W-2.s Again only the beneficiary's own civil documents must be original/certified
3) Some rogue consulates make up their own rules, such as Montreal, Dubai, etc.. and those do require certified copies, but not the Manila embassy.
4) Sure, of course, if at the interview, the beneficiary shows a horrible copy of any civil document, something that was printed on a ####### printer (I guess that is common in the Philippines), that is fuzzy, hard to read, looks suspicious or similar reasons, then sure they may ask to see the original. But these are rare isolated cases, and this is a very different story, and does not mean the original is REQUIRED, Its just their fault for giving such a bad copy that they forced the consulate to ask to see a certified copy.
5) The USA agency that I used for my K1 specializes in doing Filipino K-1/CR-1. I verified with them today, that literally nearly even single day since yesterday they have clients getting their interview, and they have never ever had anyone got 221g. They tell all clients to only give the beneficiary a copy, since its not required to provide an original or certified copy.
6) So .. sure, if you don't trust your fiancee to print out a clean copy, or if there is something very rare or suspicious about your certificate, then sure send her a certified copy to bullet proof it. For me, I am just sending her a high quality scanned copy on heavy weight paper to overkill it. It actually looks identical to the original including the certified stamp. In her barangay they just have cheap ink jet printers and copy paper that is as thin as rice paper.
In summary, for the Manila embassy, no original or certified copies of ANY of the petitioner's civil docs are required at the embassy (even at USCIS level (except for court documents to the USCIS)) ...
Sure, you can say "do this at your own risk" .. but that is just promoting unnecessary fear ... You should just say "as long as your civil document is printed normally, not fuzzy, blurred, or other printing artifcats that make it look suspicious, etc etc .. then it is absolutely not necessary. Again. my agency which has had thousands of clients over many years, as of yesterday, they have never ever heard of any such requirement and their clients have had zero issues.
