Applied for STEM OPT, Passport is expiring in Sep

Hello All,

My initial OPT is expiring in July and I have applied for STEM OPT. my problem is my passport is also expiring in September and I have applied for new passport after applying for STEM.
Will there be any issue, will my STEM OPT be approved and if approved how can I extend my I94?

Thank you all in advance for helping out each other here.
