Passport expiry when H1B visa under process

My passport is expiring in 2 weeks from now and expecting to receive new passport in this week. Currently I am in L1 visa and working here in USA. I got RFE for my H1B case. I am not sure whether it is better to include the new passport copy along with the RFE response or not. USCIS didn’t request new passport in the RFE. My attorney told that it is not required as more than 6 months passport validity was there when applied for H1B in April 2018. But I got doubt whether USCIS will approve with expired passport details.
