Foreign RN for Acute Rehab Unit

[Cloud9RN, BSN]

Hi guys. I'd like to ask some few insights from nurses currently working in the US. I am soon to be deployed next month and will be assign in an acute inpatient rehab unit of the hospital. I just wanted to know the difference between ACU and TCU when it comes to workload, patient cases etc. How does it differ from SNF, LTAC and other facilities? I am a foreign RN and I have at least 3 yrs of MedSurg experience but that was long time ago like 6 yrs ago. My current experience is in a Nursing Home. Would it be very difficult for me to transition from a being a Nursing Home Nurse to Acute Inpatient Rehab Nurse? Thanks!
