We have a man from our parish ( US) who was ordained into the Diocese of Mogadishu, Somalia about two years ago.
He felt called to become a diocesan priest, but to serve in an area that was most in need of priests.
That turned out to be the Diocese of Mogadishu.
That See is currently unoccupied, as the previous bishop was assassinated in 1997, but it is under the administration of the Diocese of Djibouti, Africa
That is where he is currently residing (Djibouti), running a parish near the border.
So yes, it is certainly possible. What is required is that your home bishop and the bishop of the diocese that you would like to incardinate in both agree.
Father did his Philosophy (under grad formation) here, but his Theology work in Africa. He already had a degree in Mechanical Engineering.
FYI, our pastor was just out visiting him a few weeks ago, he is doing well. He is one of 6 priests for the whole diocese (both diocese actually) and runs a mission, two outstations and a trade school (being an.Engineer. he chose to make inroads with the community and combat poverty by teaching plumbing, construction and auto repair )
Here is his parish
You can see Fr Mark in the corner wearing a Roman collar and shorts ( it’s 120 in Djibouti this time of year…)
