@Tod ********
thank you so much for your detailed and patient explanation. I think the strange reason is that I didn't mention is that I already booked the flight out on Sept 14th... before I learnt all what you explained here and before I checked my evisa where I readed Sept 12th. I was very relaxed thinking my valid date was until Oct 31st.
So I see 2 options here once I have renewed my insurance in the the next days.
A) I can fly out around 7th or 8th and come back before 12th. I'm not sure with this option if I will get stamped until sept 12 2025 or Oct 31st 2025.
B) Exit with the booked flight on the 14th and apply reentry, and go to immigration during October to extend 1 more year until Oct 31st 2025.
Did I get it right? Thank you so much to all for all your answers and help.
