A foreign investor is understood to be any individual not residing in Colombia and any foreign corporation investing resources from abroad in the country.
It is presumed that a person shown as a foreign investor in the various forms used for registration with Banco de la Republic (Colombian Central Bank) is a non-resident. But, all such persons must keep the documents evidencing their nonresident status.
The old law required foreign citizens to have a local foreign ID (Cedula de extrajeria), or have someone with a Cedula, to act as their official agent when signing the deed.
NOW you DO NOT need a cedula or visa, just your passport with a valid Tourist 60 or 90 day stamp. The Notary will ask you for this at the moment of signing the Deed )Escritura).
