Can a PCT application enter the Regional Phase earlier? What are the consequences on the other deadlines?

In Russia: A PCT application can enter the National Phase earlier. As for the consequences, only the due date for filing voluntary amendments, i.e. one month from the entry date, will be counted from the new established entry date.

In Eurasia: A PCT application can enter the Regional Phase earlier. In that case the deadlines that are counted from the entry date (e.g. deadlines for filing voluntary amendments and translations and for payment of the official fees) will be counted from the actual (earlier) entry date.
