The Panthers have been working with immigration officials in a bid to claim Australian residency status for the Fijian citizen. Otherwise, he risks being locked out of the country.

"He can leave the country on his Fijian passport but wouldn't be able to return to Australia," Gould told News Corp Australia.

"He would have to go back to Fiji and apply again to come to Australia.

"If he leaves Australia now, his Australian residency application would be compromised. Trying to get assistance but it's a complicated process."

Kikau's uncertain status would be a blow for a Panthers side fell out of the top four following Saturday's upset loss to Newcastle.

The Panthers are equal with the fourth-placed Dragons, as well as sixth-placed Cronulla, on 30 points with two games remaining in the regular season.

Kikau would likely be replaced by Corey Harawira-Naera should he be ruled out for Friday's game.

The Panthers leave for Auckland on Wednesday.

"We won't make him travel unless we can get him home," Gould said.

"It's not ideal in the short term but respect for the longer term that Billy is very passionate about gaining his Australian residency."
