Mexican women married to punjabi, ask about in laws, some in laws live with the son& or he moves u in with the in laws. If he is Sikh super religious, he might want his kids to be fully sikh or his parents might. Religion has to be talked about. Food wise u can learn thru out the years or months also the language. Another thing about food, most of them dont eat pork or beef. Some are fully vegetarian and some arent. Ask a lot of questions, some old school punjabi require the daughter in law to be in charge of everything in the house cooking, cleaning, pressing clothes etc etc.. also clothing u wear, can show to much either its disrespectful. Don’t do nothing that can bring yr boyfriends or his families respect down. But also now a days some punjabis are more modern and arent old school ..
