Dealing with illegal migration has been a point of contention and unity in central Europe.
Illegal migration was a key issue in elections in Slovakia last weekend, and in elections in Poland later this month.
Slovakia has faced a rising number of illegal migrants crossing as they head to Germany and western Europe.
Slovakia said last month the number of detained illegal migrants had soared nine fold, to more than 27,000 this year.
"In recent weeks, we detected and detained 551 illegal migrants at the border with Slovakia.
