The US President Barack Obama visited the Afghan intelligence chief Asadullah Khalid Friday afternoon in a hospital in Virginia.
Mr Khalid, who survived a suicide attack at a National Directorate of Security guesthouse in Kabul on December 6, received substantial injuries to the lower part of his body.
He was taken to the United States for treatment on December 15.
President Obama told Mr Khalid that he was sorry for what happened to him, asking him to contact him directly for anything he may need.
Mr Obama told Mr Khalid that he prayed for him to get well soon.
The US President's visit to the hospital was also to make sure all required services were provided to Mr Khaild.
President Obama told Mr Khalid that President Hamid Karzai is visiting the US on January 7.
President Karzai had earlier said that Mr Khalid will return to his position as head of intelligence when he makes a full recovery.
Before taking him to the US, Mr Khalid was receiving emergency surgery and blood transfusions at the NDS hospital in Kabul, than he was moved to Bagram Airfield hospital for ongoing treatment.
The bomber, who met with Khalid on the pretext of peace talks, carried the bomb in his underwear.
Khalid has already survived at least two other attempts on his life. One was in southern Kandahar province in October 2011 while he serving as the Minister of Border and Tribal Affairs, and another in a 2008 roadside bombing when he was governor of Kandahar in 2008.
Khalid was appointed head of the NDS by Karzai in September.
