Must a wife who visits her husband in another state due to work and study circumstances pray shortened and combined prayers, or is her husband's home considered her home?

If the wife only visits her husband for a few days, the marital home is not considered her permanent residence. She is treated as a traveler if the distance between her province and her husband's province exceeds 80 kilometers. She shortens her prayers as long as she is traveling, and completes them if she intends to stay for more than four days. She is permitted to combine prayers where shortening is allowed. Shortening prayers is a confirmed Sunnah, while combining them is permissible. Sheikh Ibn Uthaymeen emphasized that whoever visits their family in their former country while residing in another country is considered a traveler, even if they have a wife and children in their first country.
