This may change with the country but generally speaking, it’s a little more complicated than voting from home. You have to go to your nearest embassy to fill papers and anounce that you will be voting in country X a few months prior to the ellection.

Embassies usually get just a few ballot boxes when not only one, so you can expect a few thousands or so voting in the same box, which makes horrendous queues.

Some “more civilized” Countries also offer more efficient ways to vote when you are abroad, like voting through mail. Which is nice.
