Ill try again. There are two families both move to Bangkok for education of the children and parents as dependent, both families have the same nationality.
Family 1 enters on August 3 with a 90 days visa (Ed and non immigrant O) and get stay until Nov 1. In mid October they get extension of stay and get a stamp until 30/06/19 so total 11 months they all get exactly the same parents and children.
Family 2 enters on August 20 with a 90 days visa (Ed and non immigrant O) and gets stay until Nov 18 today they get extension of stay and get a stamp until 30/10/19 so total 14 months and 10 days they all get the same parents and children
My question is given the exact same situation why this difference ?
TLDR : Answer Summary
Two families relocated to Bangkok for educational purposes, both holding the same type of visa. Despite their similar situations, they received different durations on their extensions of stay. Family 1 entered on August 3 and, after an extension, was granted a total stay of 11 months. Family 2, entering on August 20, received a total of 14 months and 10 days after their extension. The community suggests that differences could be due to the application timing of their extensions or possibly linked to the letters from their school.
