And you cannot assume it will be 10 years from the date of the stamp.

So for example, without giving away my personal data and so using fake dates, I might have received at stamp on March 11, 1999, my first green card says I was a resident since March 12, 1999, my current green card says I was a resident since April 14, 1999, and my current green card expires April 16, 2019.

If you cannot accurately predict your green card's expiration date, you cannot complete the application.
