visit visa supporting docs question- one for each applicant?

[worldpeace]

I am trying to sponsor visitor visas for my uncle and aunt who will be applying together at Chennai consulate through TTS drop box.

1. The immihelp pages suggest separate I-134, employment letter for each applicant but I found the following on the Chennai consulate webpage.

"Please remember that with suggested documentation, it is not necessary to submit duplicates. For instance, if a couple is going to visit a relative in the U.S., one copy of an AOS (Affidavit of Support) or salary details or a NOC (No objection Certificate) or property documents is sufficient. Each applicant does not need to submit a separate copy. "

So, is one set enough?

2. Another related question. Will the drop box guys bundle both the applications together to send to Consulate or do they treat each separately as otherwise each will require its own set of supporting docs?

Thanks in advance for your replies.

1. One set for paystubs etc. are required, but you have to submit one I-134 for each person. That is what is written I-134 form.

2. They can do it together.
