I know this is a stupid question but here's a little background.
I left DR last year and came to Scandinavia to study. At SDQ i wasn't asked for the 10USD (at that time) impuesto de salida (or entrada?) and i even asked a guy at Migration departure if i should pay him and he said "no, you don't have to pay" (but i saw the woman in front of me gave him the money). I'm going back to DR in 2 weeks and i wonder if i have to pay that fee. If i have to pay for it, is it still 10 USD or has it increased? I'm born and raised dominican with dominican passport

.
Thanks in advance and sorry for my ignorance. I'm not so much of a traveller and this airport would be the first where i pay for entering/leaving a country.
