I need the information to get a visa for a Ghana citizen that wants to come to Spain, it´s a permanent visist so it must be a special visa.

Did you meet this person on the internet? Have you ever met her face-to-face?

Normally it is a tourist visa and is changed after they get into the nation.
Next it is not a Ghana visa, it is a visa for Spain, you get a Ghana visa to visit in Ghana, they get a Ghana passport and a Spain visa.

They need a airline ticket,
Their passport
Medical(medical travel) insurance

Of course you do know there is no girl and they are not coming. Ghana is the largest dating scam area in the world.
