Is it permissible for a Shia woman to marry a Sunni man without being required to change her faith and beliefs? And would it be acceptable if the children from this marriage adopt Sunni beliefs instead of Shia?
In general, marriage between any Muslim woman and Muslim man is permissible provided such marriage does not cause harm to faith or religious practice.
'Shi'a woman must do her best to bring up her children on loving and following Ahlul Bayt (AS).
Wassalam.
