he mean he can't travel in a car due to all the vibration. I will see if the relevant department could make the road as smooth as possible so he can proceed to the immigration office.
Get a doctor to go to you, after getting an agent to get the visa for you. Be prepared to pay huge amount for the services above. Get a lawyer to represent you for a long term stay or maybe a permanent residency since you can't travel in a car especially the country you are in are mostly running by car or bus. Either hired a private chopper to send you. maybe start a go fund me and get people to donate to all the expenses above.
