If you are a remote worker what's the issue (it's been one of ways to prove employment since the visa began) with providing a tax return to prove you are indeed employed? If you have been travelling and not working then a remote worker approach is probably not for you.
if people are not trusting a visa (that thousands have already entered on in the last 4 months) to a country where the visa has been issued by an Embassy of that country they probably need more support than a few people saying that they entered successfully.
