it's a bit of a pain in the ass if you want to come here on a work visa, you'll be treated like a churka slave, abused by your employer, and paid nothing if you can find someone to marry you, you have to keep flying between russia and your home country to renew your temporary visa for 3 years until you can apply for residency but if you're one of those people who left the ussr (or your parents left the ussr) for israel in the 80's/90's, there's a special type of blood visa you can get that makes the immigration process pretty simple and easy
