passport expiry for dependents (H-4 visa)

Hello Friends,

We are in India and my petition has been selected in lottery.

What are the requirements for passport expiry for dependents?

My wife’s passport expires on 15th May 2016

My daughter’s passport expires on 31st March 2016

My employment start date is 1st Oct 2015

Should I get renewed their passports before applying for DS-160?

Thank you,
