We (Permanent Residents since Feb 2009) want to invite our Parents and Parents-in-laws to US by applying Visitor Visa (B2). We both are working and Our plan is to sponsor (I-134) for my Parents through me and my in-laws through my wife. we want to let my parents apply for Visa first and then my in-laws after a month.

1) Can we do this?

2) If we two sponsor individually to our parents, can we include our joint income and our joint savings in our separate I-134's (Sec 7).

3) Since my wife is working, Should i include her as Partially Dependent in my I-134 (Sec 8). In this case, Should i need to submit her's employment verification letter.

4) In my wife I-134, does she need to include my parents name as Previously Submitted Affidavits. I am thinking NO.

Please let us know.
