I have heard that wage garnishment in NC is illegal for personal debt?

I moved to NC in September and was sued by a former landlord in Missouri for past due rent after I moved here. I changed employers moving from Missouri to NC. My employer has branches located throughout NC and Missouri with the corporate headquarters in OHIO.
The landlord has issued a garnishment order. I have heard that the landlord is unable to collect via garnishment in NC unless they issue the garnishment to the employer I worked for in Missouri AND I still work for them. Is this correct?
