What is the ruling on working in a foreign bank and receiving its salary, given that I am married with two children and have not found any other work?

Usurious dealings must be abandoned immediately, in compliance with Allah Almighty’s command: (O you who have believed, fear Allah and give up what remains [due to you] of interest, if you should be believers). This is also because everyone who assists in usury shares in the sin. The matter may become somewhat difficult, but trust in Allah Almighty that He will provide a way out for you, as He says: (And whoever fears Allah – He will make for him a way out And will provide for him from where he does not expect), and His saying: (Allah will bring about, after hardship, ease), and His saying: (For indeed, with hardship [will be] ease).
