EAD Renewal and Auto extension query

H4 EAD is valid till March 2024, I-94 and H4 Visa is expiring in June 2024 so should I file standalone EAD renewal now with June i-94 validity?

Our Visa extension will be file together with H1 in January or February so should we do all it together later?

What is the best possible scenario for my EAD for renewal, Am i eligible for automatic EAD extension If i file before October 26, 2023 or It’s same if i file it together in Januray/Feb 2024?

Apply H4/EAD with H1B and use premium processing for H1B.
