Hello All,
For you kind information, Yes H1 Candidate can drive Uber. I am not sure of Lyft. But for sure you can drive Uber. Because i am driving as H1 Candidate. I did lots of study and contacted Uber service to confirm and finally driving for over a year.

Uber driver are independent contractor. So they are not an employee. For H1 candidate, they can't have more than one employee. So if you drive Uber, you are the owner/sole proprietor. It works same as H1 owning his/her own business and share the profit. Me personally, i get W2 (salary) from my employee and for driving Uber i will receive 1099. When you file a tax for the year, H1 should not have more than one W2 but as many 1099 as he gets. There are many H1 who owns their own business apart from their regular job. When you receive 1099 you include them in schedule C at the time when you file a tax. So 1099 does not act like you are working for different employer.

So for your better information. I have no problem transferring my H1 even though i have been driving Uber. I just got my labor approved with no problem.

So the Answer is "YES". Utilize your time and convert your extra time into money.

Good LUCK.
