Is it necessary for the person who has got a visa to enter a non-Muslim country to abide by the laws of that country in all fields, like traffic laws, laws regarding work and employment, etc.?
Answer
If he has given an undertaking—even if indirectly [as is implied in the immigration documents]— to abide by the laws of that country, it is necessary for him to fulfill his commitment in issues that are not contrary to the sacred laws [of Islam]. As for example, it is necessary to obey traffic regulations regardless [of the fact whether you have given a commitment or not], if not obeying those rules could eventually lead to harming people’s lives and properties which are sacrosanct [in Islamic laws].
