My man Grassroot,AS6 is a special code only used by uscis to category your GC.If they don't tell what AS6 stands for,you're not gonna know it's a category on GC as a result of asylum.I don't see how peolpe in your home country or your employer or other people in US and all over the world are gonna know this.Even if you work for uscis,if you don't belong to the GC section,you're not gonna know this.It's too much technical.On your Permit,it's marked RESIDENT.There is no where said AS6 on your Permit,nor refugee or asylee.On your RTD, you see the title REFUGEE TRAVEL DOCUMENT.At your port of entry,the IO stamp your PERMIT.Again,if you show your GC or your Permit to people,Nobody is gonna know your asylum's origine except people in system like you or me.But, if you show your RTD to people,your asylum's origine will be known.Even homeless knows you're an asylee when he looks on your RTD.
