Please only write what type of entry stamp your NON-EEA Family member has received on their passport while you have recently entered the UK
You can simply write a few lines about the stamp e.g. whats written in the stamp or may share the photo
You are more than welcome to share if no stamp was placed on your passport/s at the entry of any British port and you have successfully and legally entred the UK and now in the process of making (or have made) an application for Surinder Singh route.
Mods, a very genuine request to please keep this post specifically about the entry stamp. And, may one of you please steer the users to how to upload a photo. Many thanks
