YOU DO NOT NEED TO LEAVE THE COUNTRY OR RENEW YOUR TOURIST VISA AFTER FILING FOR TEMPORARY VISA APPLICATION!!
When you submit your application, you will be given a receipt of sorts for a certain number of months. If that should expire, and immigration has not approved, rejected, or requested more information regarding your application, you need to go back to the immigration office and they will issue you an extension. Many, many people have this problem especially when immigration in Santiago gets really slow in reviewing applications.
This is a quote from an official ruling we requested from immigration on the issue for our clients:
En la copia de la solicitud que le fue entregada, se específica un plazo de validez del documento, periodo en el cual la Autoridad resolverá su petición, ya sea aprobando o rechazando. La validez del mismo puede ser ampliada, si excede el plazo de resolución.
