Automatic ReValidation with older stamp

[jinneebhat]

I have got 3 stamps on my passport

L2 expired in 2008

H1 expired in 2010

I once availed AVR in 2012 when I was on H1 status

Now I converted from H1 to L2 COS

Can I visit Canada and return to US using old 2008 L2 stamp and new approved L2 petition using AVR?

Yes, the old expired L2 Visa makes no difference.
