I've sent an e-mail to support@lifemiles.com with all my details and they replied:
Dear
It is my pleasure to greet you.
Regarding your inquiry, I would like to inform you that up to this moment, Elite status match procedures are not available in Brazil. However, if you are interested on becoming part of our Elite program, I would like to inform you that you may purchase an Elite status at the following prices:
Silver: $1,200 USD plus taxes
Gold: $2,200 USD plus taxes
Diamond: Not available for sale
Once the Elite membership is purchased, the new status will be updated automatically within 24 hours. From that moment on, you may enjoy the benefits that correspond to the acquired elite level. Membership follows a one-year term and starts from the moment of purchase. You may find additional information about the status purchase by clicking on this link.
On the other hand, we recommend you to add your official ID number, mailing address and current phone number to keep your profile updated, under the Information & Preferences section.
Thank you for your interest on our program.
Kind regards.
