Hey Shazoozle,Hey Gakau,
Apologies for the late reply to your question, I had been extremely caught up with work and hadn't had the chance to come and look at this till just now when I was going to make another update on the post. Unsure of where you originally are from, but a notary affidavit would definitely be enough to say that you are not wrapped up under National Service Liability and do not have to go back home in order to serve.
With myself, currently being within the UK, I was unable to receive one, so I had just collated a bit of information from different sources as evidence and sent that over, assuming that it was accepted since I moved through the application process hastily. However, if you are able to get a notary affidavit, then I suggest you do so as that would definitely help.
I'm in Kenya. I uploaded the documents, went through, got a call from capita, passed my triage but now there's one more hurdle. ( check your inbox).
