West, when if you were to transfer miles into your United Mileage Plus account, those miles would be miles which were not flown on United Airlines, and they would not count. The underlying basis for this is the distinction between flight miles (sometimes referred to as base miles) and program miles (sometimes referred to as base + bonus miles). Only flight miles generally qualify you for elite status with few exceptions.

E.g., if this calendar year, you were to fly 80,000 miles on a Star Alliance partner's flights, and were to have specified United Mileage Plus as the FFP to credit, and then flew another gazillion miles on that partner, crediting those miles to that partner's own FFP, and then transferred the miles using something like the Hilton HHonors program as an intermediary (and accepting the significant devaluation in the number of miles), United Mileage Plus would not owe you Premier Executive 1K status, only Premier Executive status. They may choose to grant 1K to you based on unpublished criteria, but they don't owe it to you.
