@Wylie ******
yes, that is the main point of my post as in the old times with the TM 6 paper form I/we filled the visa Number space with the re-entry permit number....but now with a new passport filling the visa Number space with the re-entry permit stamped/ linked on the old passport would maybe create confusion in this new TDAC system.
So I/we will leave that space empty. Thanks all 🙏
