Tourism
You can apply for a visa at the VFS Global office in Baghdad - https://www.vfsglobal.com/en/individuals/index.html. Please note that your passport will be sent from the VFS Global office to Amman, Jordan for further processing as the Embassy in Amman will decide whether you are to be granted a visa. The passport will be returned to VFS Global when the case is settled.
You may contact the Embassy of Sweden in Amman which is the regional migration hub in the region.
