Can I register with umbrella company if I hold student visa

[sheepherder]

Hi there,

I am holding a student visa, i am working part time for a company. However, due to the policy changed at my company, they want me to work as seld-employed/ freelancer. Obviously it would in breach of student visa's contition. Someone suggested me to register with an umbrella company. I am wondering if Home Office would consider umbrella company as an employer?
