International student - International Student Services (ISS) open or closed?

Does anyone know whether ISS is open or closed during this time? Despite calling several times last week and throughout this week, I cannot get hold of any staff members working for ISS. Their phone’s message inbox is also full so I cannot leave any messages.

If anyone here is currently attending the College Station campus, can you please let me know if there are staff members working there or not? Or is there a holiday break for most staff members at the campus at this time? I would really appreciate it.
