I've no idea. I was under the impression that NHST&T kits could be taken overseas, indeed the quid-pro-quo would be to ask people to use them twice a week while overseas. If people do the right thing then it's essentially the same as using Qured anyway - it's just the video supervision, which doesn't add much extra safety for those who use LFDs in daily life. It's less of a problem than it may look, testing is now available almost everywhere, and generally cheaper than the UK or even free.
