The Nigerian, 31, arrived from Shanghai Shenhua last January on an initial six-month loan, before the club extended the deal until this month.
Ighalo has now named MLS as his desired destination.
"I have been watching MLS and the league is doing well and I would like to play in the MLS," the Shanghai Shenhua loanee told ESPN. "I have to wait for offers and if the opportunity arises, I will take it because the league is doing well and it is a good life and I would love it.
"Lots of players go there. Even Gonzalo Higuain from Juventus is there, also Giovanni dos Santos. Why not? I would like to go there if an opportunity arises. Being an experienced player, going there, doing well. It is an opportunity if it comes for me.
"The David Beckham club [Inter Miami] is growing, so if an opportunity arises why not?"
