The extensions are only given when your initial document is running out so it's not worth going until you're on your last fortnight of your Tourist Card. You will have to show proof of your financial capabilitites for the period of your stay - a credit card usually does the trick.

If in Mexico City, To get to the 'Instituto Nacional de Migración' by public transport, take the 'Metro' (underground/subway) (see PDF Metro map) and get off on the orange line (7), at the Polanco station.

Once you're upstairs, take the exit to the left and take the bus just by the exit; get off at the 'Palacio de Hierro' store, the driver usually announces it but it's not a bad idea to request that he let you know (¿Me avisas cuando llegamos al Palacio, por favor?).

From there take the street to the right of the 'Palacio' and walk to the end. The Immigration Institute is on your left.

A further option is to take the same bus from the 'Metro' station Chapultepec, on the pink line (1). (PDF map of the 'Metro').

If outside Mexico City, below we provide contact information for the immigration offices in each state.
