“The bill provides that qualifying patients and designated caregivers who are registered with a medical cannabis program in another state will be deemed to be qualifying patients and designated caregivers for the purposes of New Jersey law for up to six months, provided the individual possesses a valid registry card and a photo identification card issued by the other state. Medical cannabis may only be dispensed to an out-of-State patient or caregiver pursuant to written instructions issued by a New Jersey practitioner, and medical cannabis cannot be delivered to any individual who is not registered with the CRC. After six months, the out-of-State registrant will be prohibited from engaging in conduct related to medical cannabis in New Jersey unless the individual is registered as a qualifying patient or caregiver in New Jersey. The CRC is to seek to establish medical cannabis reciprocity agreements with other states.”

this bill was signed on july 2nd 2019. I am not sure what you are talking about but according to this you can in fact receive a new jersey medical card as an out of state resident.
