Mrs Hekmati once more makes the trip back to Iran to visit her son. This isn’t like visiting Canada or Western Europe. Like Amir did in 2011, she had to go to the Iranian Interest desk at the Pakistani embassy. There she would submit her request and have to wait for approval to travel back to the land of her birth.
The whole time she would be wondering whether she would be approved, or if Amir would be sent back to trial. 
On the 23rd of March she arrived back in Iran. She was, however, denied permission to see her son. Try to put yourself in her place for a moment. There is, of course, the joy that the death sentence has been lifted, but then the frustration of travelling half a world away, only to be turned away. 

Her emotional pain must have been palpable.
