The 28-year old defender joined the club in July this year from Real Salt Lake but after finding out the club has a tight financial situation that only allows him to be payed as he plays, a new home might be his best option.
"After arriving a little late into July, I found it very difficult to even get a try-out at any of the 2.Bundesliga teams due to the teams being set in their squads or financial issues," he told Soccer365.
"I got lucky in September that an old friend of mine from my St Pauli days, Harald Gaertner, offered me the chance to train and get myself fit at 3.Bundesliga FC Ingolstadt, with the chance to stay on if finances and on the field appearances worked out."
Joy has been linked with a move elsewhere in Europe or a return to MLS and says he will decide on his future very soon.
"I am now back to top fitness and raring to go again, but the winter break is coming up and it looks like finances at the club and doubt over my fitness might prevent me from staying in Ingolstadt," he added.
"I have been training and playing here in Ingolstadt with no salary for the last four months and there has to be a point where I start to earn money again. It looks like I might have to move away from Ingolstadt to find that.
"I am going to take my time over the Christmas break with my family and then make a decision where I will move to next," stated Joy. "Family is very important to me, and with a daughter to look after financially it's very important I make the right move."
