DS-156 questions

[skhelpim]

I have sent a support affidavit for my in-laws who are visiting us. That I would take care of all expenses for the trip. HOWEVER my In-laws are paying for the flight tickets. The DS-156 has a question who will pay for the TRIP ? What is the correct answer here .
Should it say my name, or "self" indicating in-laws themselves are they are paying for the flight ticket.

Question 2:

Since I have signed (solely) the affidavit of support, should the invitation letter be from ME alone to invite my IN_LAWS or can it be from both My Wife and ME.

thanks

1. "Self" is ok. they may have to show the proof that they have enough money.
2. It can be either only from you or both.
