In short:

The United States has stopped processing all immigration requests relating to Afghan nationals.

The decision comes hours after Donald Trump labelled the shooting of two soldiers in Washington an "act of terror" committed by someone he said was from Afghanistan.

An advocate for Afghans resettled in the US is concerned the shooting will be leveraged for political purposes.
