Outside of a legal abortion, killing a fetus is a homicide at least in some states. How can a homicide not mean the fetus is a citizen whose rights have been violated in those states? I don't know why it isn't a homicide in every state, but well, politics.
Roe vs Wade simply restricts states from outlawing abortion. Being overturned won't make abortion throughout the country illegal. But it would allow individual states to decide the matter. Just as the states continue to have the right to determine for themselves what constitutes homicide. As for the individual states you mention, I highly doubt the protection of the fetus in these states is dependent on citizenship, pretty sure the law is the same regarding a fetus of a foreigner.
