Is it possible to confirm a distance learning diploma abroad. Are you interested in Canada, the Czech Republic, Germany?

Question

Distance learning

Good afternoon! I plan to transfer to a correspondence course (specialty - construction of bridges and tunnels) at this time I will already work in my specialty and gain experience.
The only thing that worries is whether it will be possible in the future to confirm the diploma of a part-time student abroad, namely, in Canada, the Czech Republic or Germany?
