Tony Mowbray's side are scheduled to play Morton in the fourth round of the Active Nation Scottish Cup on Saturday then face SPL matches against Falkirk, St Johnstone, Hibernian and Hamilton before the end of January.
N'Guemo could potentially miss all five games but regardless of how long he is away from Glasgow, he will try to keep in touch with Parkhead via the internet and text messages.
"It's a great honour for me to have been chosen to represent Cameroon at this tournament but of course I am disappointed that I will miss some games for Celtic," he told Celtic View.
"The tournament runs until January 31 when the final is played and I want to help Cameroon to that stage.
"However, I don't want to miss too many games for Celtic.
"It's a hard situation, but all I can do is play my best and try to help Cameroon. After that, we will see what happens.
"I don't know how many games I will miss at the moment but I will make sure I find out the Celtic score as soon as possible after the fixtures.
"I will have internet access at the team hotel and I will also call or text a few of my Celtic team-mates to find out how we are getting on.
"I have to think of Cameroon this month but Celtic will always be in my thoughts."
