Yeah, idea of country B inserting enough controllable voters into country A is likely very difficult in reality if A has a sufficiently large population. Could be possible for smaller nations. The question there becomes the economic or strategic value that nation might offer in order to justify this type of action. For example, a bunch of countries in Europe have populations between 5 and 10 million. The question there becomes: How many controllable voters would you have to inject into such nations in order to have degree (not absolute) or control in elections at various levels, from local to national? I don't know enough about their voting systems to be able to guess. Obviously, as you get to nations with tens of millions of people this becomes harder and harder to execute. The part that isn't hypothetical is the idea that citizens who have left nation A can cast votes remotely and affect those living in country A (at a local to national level) while not suffering the consequences of their votes. This is real today. Obviously, if expats from A are obligated to pay taxes in A while living abroad, they should have the right to vote. A deeper look is likely required because the rule might have them paying zero taxes (they have to file, yet credits make it zero) or the voting ought to be restricted to the kinds of taxes they pay. For example, they get to vote on national elections only and can't vote on state/provincial elections. I know many people living abroad for decades. None of they pay taxes. Some of them vote. And that's the point. They are completely disconnected from the consequence of their vote. I don't think that's right.
