overstay effect on relative?

[drzero]

My wife is a U.S. greencard holder. Her mother is here visiting us on a visitor visa. If her mother overstays the visa, could that affect my wife in the future upon applying for citizenship? Does a relative's overstay affect a greencard holder?

Generally, it should not affect.

However, it is best not to have any overstay.
