Er bod y dyddiad cau i wneud cais i’r Cynllun Preswylio’n Sefydlog i Ddinasyddion yr UE bellach wedi pasio, mae holl ddinasyddion yr UE a oedd yn byw yng Nghymru cyn 31 Rhagfyr 2020, neu unrhyw aelodau o’u teulu sydd wedi ymuno â nhw ers hynny, yn dal i allu gwneud cais hwyr ar sail resymol.

"Although the deadline for applying to the EU Settlement Scheme has now passed, all those EU citizens who were resident in Wales before 31 December 2020, or any family members who have joined them since, can still make a late application on reasonable grounds. Children of EU citizens can make or have a late application made on their behalf indefinitely.
