Thank you BillieBob for your reply and information ,
Now i can be relaxed knowing that i can at least let go of renewing my IR a year or two .
Regarding doing the TR without a valid MEIR , so if i get hired by an airline ,i do the TR , and then renew my ME IR ? Or the multi pilot IR which is done on the multi pilot aircraft in an airline is different and does not depend on the status on my SP MEIR ? How is the Multi pilot MEIR connected to single pilot MEIR ? Im confused
