Visitor visa-Imp question

[nsnb7]

Hello,
My parents when they filed DS-156,had mentioned that they themselves will pay for the trip.
Will this be okay/recommended?
If I yet send my sponsorship letter(I-134) etc,will that do?
What are other important things to keep in mind if parents have mentioned that they will pay for the trip.

Please guide.

Thank you all

I they self sponsor you dont need to send I-134.

If self sponsored one most important factor: -

1. Must have a very strong financial background and proof of funds to support their trip.

How much balance should be sufficient to sponsor two adults and two kids?

Thanks
