No. The great part about USCG Licenses is that you don't lose them as you upgrade and renew.
Only if your new license was higher in the scheme for the same route and capacity would it be removed from your MMC as it becomes redundant.
A common example is when someone upgrades from 200 GRT Near Coastal Mate to 200 GRT Near Coastal Master.
Because Master is higher than Mate but everything else is the same there is no reason for the Mate to be written on your license as a Master can legally serve as a Mate when they are qualified for that tonnage and route but the opposite is not true as a Mate can not serve as a Master. You don't ever need to worry about losing a license due to professional development.
