There is no citizenship programme in the countries you mentioned. Paraguay (and Uruguay, etc) has a simplified residency option and a residency by investment programme. If you need an entrance visa in Paraguay, it will be a difficult task to get it without a job or investment. You may do it but will be difficult. If you do not speak Spanish, it is possible to get a job in Paraguay, however, it will be also difficult. Spanish is a simple language, start learning it from yesterday to boost your chances.
