Norine Brunson (pictured above outside Harmandanli Detention Centre where her husband has been kept) spoke for 20 minutes with US Secretary of State Rex Tillerson in the Turkish capital Ankara about the case of her husband, Andrew.
Mrs Brunson said: "I do not know what will come of it, considering the sensitive period Turkey is in, but was grateful for the opportunity."
She reported that Mr Tillerson said he was informed any charges against her 49 year old husband were "about to be handed down".
Andrew and Norine, who have been involved in church ministry in Turkey for 23 years, were detained in October 2016 over a bid to renew their residence visas.
Two articles published by pro-government Turkish newspapers in December 2016 contained allegations that Andrew was involved with Islamic cleric Fethullah Gülen who Ankara suspects of organising a failed coup in July 2016.
A protestant pastor leading the legally-registered Izmir Resurrection Church in Izmir on Turkey's Aegean Coast, Andrew was also accused of links with outlawed Kurdistan Workers' Party (PKK).
Three weeks ago, Turkish Prime Minister Binali Yildrim denied speculation Brunson was a political bargaining chip, to help encourage the US to extradite Mr Gülen, who is in self-imposed exile.
Earlier this week, Andrew Brunson was visited in prison by US Embassy officials when he hand them a letter addressed to the US president Donald Trump.
Reasserting his innocence, he described himself as a political prisoner, adding "I plead with my government -with the Trump administration- to fight for me.
"Please do not leave me here in prison."
Mr Brunson was denied access to a lawyer during the first two months of his detention and he has yet to be shown any evidence he is a threat to the national security of Turkey.
In a crackdown allegedly targeting what Turkey calls the Fethullah Gulen Terrorist Organization, tens of thousands of judges, journalists, military personnel and others have been jailed following the attempted coup last summer.
