The 28-year old Australian international has been granted a UK work permit but still needs a visa and once that is obtained, he will be free to join ‘Gers as was stated on the club’s official website.
"Rangers were successful on Friday in gaining a work permit for Australian star Matt McKay but there is still some paperwork to be done before he can join up," read the statement.
"The SFA endorsed Rangers' application and then it was passed by the UK Border Agency.
"However, the 28-year-old now needs to gain a visa in Australia before coming to Scotland.
"The Light Blues hope this process can be completed in the early part of next week and he can then travel to Scotland.
"Depending on when this takes place, McKay might be in a position to train with his new team-mates and stake a claim for inclusion in the squad for the Aberdeen game on August 28."
