Travel on Visitor visa

[Virgo]

Hi,

I sponsored for my mom and she got her visa. My husband sponsored for his parents, and they also got their visas. (Both of us on L1 visa working in USA)

1. Now we want our parents to travel together to visit us, is that ok?
2. can they go through the immigration together talking about their own sponsorers if asked (or showing the seperate letters we give) because except for my Father-in-law, others cant manage in english

Appreciate your early reply.
