How can I make my Chinese friend visit my country?

Documents your friend need to provide:
1.passport with at least two blank pages and it should be valid for at least six months
2.copy of the personal information page of his/her passport. If he/she once acquired the Columbian visa, a copy of the latest Columbian visa is required.
3.filled application form with his/her signature.
4.two 3X3.5cm color photos with white background
5.other required documents:
1). Financial documents that can prove he/she has enough money to cover his/her expensive in your country
2). If he/she is invited, then the one who invites him/her must provide the documents that he/she can cover the applicants’ expenses in Columbia.
3). Copy of the return air ticket booking order. It must be a valid one provided by the airline, which must show the booking number and ticket number.

Then he/she can go to the Columbian embassy in PRC to go through the application.
