I have an under consideration stamp until October 7. I understand I need to close this loop. Do I return to the temporary immigration office or CW for this? Also, do I need to book an appointment online? Originally, they said I did, but I’m looking at it right now and there is no option for under consideration. The ‘objective/counter’ options have changed. Counter K is no longer listed. 
TLDR : Answer Summary
The user has an under consideration stamp valid until October 7 and is seeking clarification on whether to return to the temporary immigration office or another location for resolution. They also inquire about the need for an appointment, noting confusion over booking options. A comment suggests that the user should return to the designated location on the date indicated on the stamp and that appointments are not required.
