The Dutchman has been frozen out of Andrea Stramaccioni's side since September due to a pay dispute, and the Istanbul giants confirmed they were interested in signing him earlier this January.
A fee was swiftly agreed with the Nerazzurri over a transfer of the former Real Madrid man to the Turk Telekom Arena, but the player stalled over accepting their offer.
However, the Turkish champions have now announced that Sneijder will soon ply his trade in the Super Lig.
"The club have reached agreements with both Inter and Wesley Sneijder over a transfer," an official statement read.
"The conditions of the agreement will be announced when the player has passed medical checks. In addition, we will announce his time of arrival."
Galatasaray are currently top of the Super Lig.
