What form do I need to issue to my contractor who is a foreign profit corporation?

[Gin Zhuang]

Hi everyone, 

I want to issue 1099 to my contractor to be on the safe side. 

1. what 1099 should I issue to them? Should it be 1099-NEC? If not, what form? Do I need to submit 1099-NEC to IRS? 

2. If the contractor used subcontractor for parts of the work, do I need to give the 1099 NEC to all the subcontractors too? Or the contractor will take care of giving these forms to the subcontractors? 

3. I found my contractor is registered as a foreign profit corporation in North Carolina. They say the reason that they are called foreign profit corporation is because they originally founded in NC but now they operate in Georgia. They do not need any other form other than 1099-NEC. Is this true? Should I still issue 1099? Other than 1099, any other form should I give to them? 

Thanks,

Jade
