I've dealt with some related issues to this, but in the EU jurisdiction(but am familiar with US landscape). 1: You are not prohibited from working with Russian developers who currently reside in Russia. The biggest issue is figuring out a way for you to pay them, but that sounds like its being taken care of by the company. 2: You ARE prohibited from exporting consulting services to Russia, to either physical or legal persons, for "enterprise management software and design and manufacturing software": https://ofac.treasury.gov/faqs/added/2024-06-12#:~:text=14071%20(the%20%E2%80%9CIT%20and%20Software%20Services%20Determination%E2%80%9D)%2C,%3B%20and%20(2)%20IT%20support https://ofac.treasury.gov/faqs/added/2024-06-12#:~:text=1407... 3:Just contact OFAC.
