What is the ruling on working in infidel countries, especially if the questioner is from Islamic countries that fight adherence to God's law and torture those who adhere to it?

The basic principle is that it is not permissible to emigrate and reside in lands of disbelief. However, it is permissible for someone who does not feel safe for himself, his religion, or his family in his own country, and cannot find a Muslim country to shelter him or finds it difficult to do so, provided that he feels safe for himself and his religion in those lands. He must strive to preserve his religion and minimize mixing with people and being present in places of temptation.
