Charlie has seen some troubles recently, which involved his situation at LAX airport in October, where cocaine was detected on him.
With series three of the show being confirmed, it is unclear whether Charlie will be allowed to return to the States for future filming endeavours.
In a carefully worded statement, Heaton said he was working to 'rectify' the situation, which is said to have occurred after sniffer dogs detected the cocaine on his person.
'My planned travel to the U.S. last week was affected by an issue at U.S. immigration, and I am working to rectify it as soon as possible,' the 23-year-old told People magazine.

'I do want to clarify that I was not arrested or charged with a crime, and cooperated fully with the U.S. officials at LAX.'
Following the drug's detection, Charlie was questioned before being sent back to England on a return flight, and was unable to attend the premiere for the second season of Stranger Things.
'I’m sorry to all the fans and my Stranger Things family for missing the premiere,' he said. 'We are all so proud of this season and I would never want this story to negatively impact the show.'
Charlie's mother and sister previously said a small amount of cocaine found its way on to his wallet at a party two weeks earlier, or at a bar or at a shop without his knowledge.

Family of the actor say he has never done drugs in the past and was not under the influence at the time he was stopped at the airport.
Charlie has since undergone tests, including a hair and urine sample, which have come back all clear, according to his family.
They are now hoping the 'misunderstanding' blows over 'sooner rather than later' to allow the British star and continue filming for Stranger Things.
But they have criticised how Charlie was treated by US officials, claiming he was interrogated for three hours and wasn't allowed to call anyone or ask for a lawyer.
They blamed his treatment on his TV star status and claim he was used 'as a target'.

Speaking at the family home in Bridlington, east Yorkshire, his mother Michelle Lowe, 50, said: 'All that rubbish, it's completely fabricated. I know that but that's all I'm allowed to say on it.
'He's never done drugs in the past. It's completely made up, that's what papers do. I'm not his agent, I'm just his mum so I can't really say too much.
'He is sort of between here, London and America. It would be awful if he wasn't allowed back to America to film but I don't see it shouldn't be.
'He has proven his innocence. It could happen to any of us, you go to a bar or a party. It's just unfortunate really. 'I know that's what has happened. I hope it blows over.'
His sister Kayleigh Heaton, 32, added: 'It could have come from anywhere. He wasn't carrying drugs, he wasn't high. He's had tests and they have come back clear.
Romance rumours: Charlie and Natalia have been spotted cosying up on a number of occasions (pictured above in May 2017)
'He not got it in his system or anything. He was at a party two weeks before and obviously when you're at a party anything can happen.
'You leave your things on the side when you're having a drink. It could be that he was at a shop, it be on a note. What they've done is wrong, they didn't give him a chance to call anybody. They didn't give him a chance to have a lawyer.
'They put him in a room for three hours and just interrogated him and interrogated him, so it wasn't done correctly.
'They didn't follow procedure. I think they saw him, they noticed him and they used him as a target. He wasn't carrying anything, he wasn't under the influence or any drugs. I think it's just a misunderstanding.
'He's been unfortunate where he's been to a party, somehow cocaine has got either on his wallet or on his cards, we're not sure.
'He didn't know anything about it, he went to the airport to fly, they checked and he is racking his brain about how this could happen. He hasn't done anything, he wasn't carrying anything. He's had tests that have come back clean.
'He has had hair sample, a blood test and urine sample which are absolutely clean. A Hair sample can last up to five months so that proves he hasn't taken anything. I think it will be fine because it's not like he has done anything.'
Due to his demanding schedule filming hit-show Stranger Things in Los Angeles, Yorkshire-born Heaton is not believed to see his son regularly.
The youngster lives with his mother, who performs in the band The Big Pink, in London.
It is now feared that Heaton could be barred from entering the US in future - meaning he could struggle to take part in filming for Stranger Things.
