Yes, you have one important advantage if you want to utilize the Paris Convention priority.
If you file a trademark application in a second country within six months of your original application date, you can claim the earlier filing date as the priority date in the new jurisdiction. This means the new application is treated as if it had been filed on the date of your original application, which protects you against anyone who filed a similar mark in that country in the intervening period.
Outside of that six-month priority window, an existing foreign registration provides limited practical advantage in a new jurisdiction. It may serve as supporting evidence in acquired distinctiveness arguments, but it does not influence the examination process itself.
