Has anyone been there ( main office on Avenida Independencia in Guad.) recently ( this year) to pay the IMSS annual fee ?
If so, how are the crowds ? does one still have to be inside and wait in various waiting halls which are very crowded and for about 1-3 hours to finsh all the steps ??
Can one wait outside in the street instead ( and be called when one's turn is up? )
any input on the safety of being there is appreciated.
