However, he is 23 years old and has played for the French U21 team in one match but because he did so before he turned 21 years of age it is believed he would be able to still play for Poland.
Let's refer to what FIFA says:
If a Player has more than one nationality, or if a Player acquires a new nationality, or if a Player is eligible to play for several Associations’ teams due to nationality, he may, up to his 21st birthday, request to change the Association for which he is eligible to play international matches to the Association of another country of which he holds nationality, subject to the following conditions:
(a) He has not played a match (either in full or in part) at “A” international level for his current Association, and if at the time of his first full or partial appearance in an international match in an official competition for his current Association, he already had the nationality of the Association’s team for which he wishes to play.
(b) He is not permitted to play for his new Association in any competition in which he has already played for his previous Association. A player may exercise this right only once.
As mentioned, Obraniak is 23 and the request must be made before the age of 21. I'm not sure if he has made a request or not but it seems unlikely that it would drag out for years. Beyond that, looking at the Cantoro situation - who played for Argentina in the U-17, he was deemed ineligible to play for Poland despite the fact he hadn't played beyond his 21st birthday for Argentina either. So in either case, it does not appear likely he will be able to make the switch.
