Currently H1b Academic, COS to F1 and future COS to H1b?

[kailing]

Hello friends, I’m currently on an H1B academic visa and plan to pursue a PhD in the near future. Consequently, I’ll need to switch to an F1 visa. Based on the current explanation, the F1 to H1B COS wouldn’t incur the $100k fee. However, I’m not sure if this applies only to current F1 students or also to future F1 students like me. Could someone clarify thishttps://100001.onl/ https://1921681254.mx/ ?

Thank you in advance.
