if you have any other country valid visa i.e. UK, US or Schengen without PR you can enter into Mexico without visa on RTD. I travelled once and i had valid UK visa without PR. entry was very smooth and at Mexico immigration she asked me to provide PR i said it is under process than she asked do i have any other valid visa i said yes UK then she look into my visa and stamp on my RTD.Does anyone know an agency that can help with visa applications (Mexico) ?
