Rangers are set to take strikers Sunil Chhetri and Jeje Lalpekhlua for trials.
The pair are set to arrive in Glasgow this month and will train with the first-team squad at the club's Murray Park training complex.
Chhetri, 27, is an India international who currently plays for I-League side Mohun Bagan, while Lalpekhlua, 20, also capped for the national team, is regarded as one of his country's most promising young talents.
Rangers chief operating officer Ali Russell said: "Sunil and Jeje will be assessed at Murray Park next week and will have every chance to impress the management team. Both players have excelled in the I-League and now have the chance to train with Rangers.
"The club is attracting interest globally and there is now a huge appetite across the Atlantic following the recent signings of USA captain Carlos Bocanegra and rising star Alejandro Bedoya."
