B2 Extension impact on its renewal

[Imm_SF]

Hi,

My parents' B2 visas are expiring next year (August 2018) and they would be applying for renewal accordingly early next year. They are here in the US right now and have their current stay until August 2017. I plan on extending their stay through December 2017 as we are expecting a baby in October. Will their extension application have any adverse impact on their B2 visa renewal next year.

Thanks.

Probably not as long as you provide valid reason for extension.
