To me
กรอบระยะเวลาการรับเข้าพักอาศัยที่ยังไม่สิ้นสุดลง
Can only be referring to permission of stay.
If not what is the timeframe that is being referred to, rental contract, leasehold, hotel reservation However how would this apply to somebody whose rental contract exceeds the permission of stay or somebody who owns their own property.
The other aspect, and maybe somebody can clarify, when informing of residency to the relevant officer is a timeframe of residency tenancy stated or requested.?.( I have not completed one myself so do not know)
