RFE for 485 letter...What documents needed?

[aniyan]

We received a letter from VSC - RFE for our 485. It states that we need to provide evidence that my family will not become public charge in the US. Of the options it gives us, we can submit the I-134 (an affidavit of support on their behalf by me) to satisfy the requirement. However as part of the I-134, one has to submit in duplicate the following:
1. letter of employment
2. bank statements
3. Income tax returns etc.

If anyone has done the same things, please post online.....

Thanks.
