UPDATE to last post concerning remote, contract models or staff

A U.S. company can legally hire a foreigner for contract work by classifying them as an independent contractor, meaning the foreigner would not need a work visa and would be responsible for their own taxes in their home country, as long as the work is performed outside the U.S. and the company does not exert too much control over how the work is done; essentially, only managing the final deliverables or services
Key points to remember:
Independent Contractor Status:
The key is to establish a true independent contractor relationship, where the foreign worker operates as a self-employed individual, not an employee of the U.S. company.
No Work Visa Required:
As an independent contractor, the European worker does not need a U.S. work visa to perform contract work.
Tax Compliance:
The foreign worker is responsible for paying taxes in their home country according to local regulations.
Contract Agreement:
A clear and detailed contract should be established outlining the scope of work, deliverables, payment terms, and the independent contractor status.
Important Considerations:
Laws related to U.S. / foreign workers via contract work are subject to changes as time passes. Abiding by both country laws is vital. Some countries may not be compatible with U.S. contractor work.
You should research yourself on this matter...based on your own country. As every country is different to a degree. We do not hire from countries thar are considered outside of Nato alliance. Sorry.
Control Over Work:
Any company avoid exerting too much control over the worker's day-to-day activities to maintain their independent contractor status. Yet, is still able to follow standards of that company.
Payment Methods:
Utilize international payment methods like wire transfers to pay the contractor. Online digital pay apps. PayPal is one possible. However, not all countries offer PayPal.
Alternative Options (for situations requiring more control):
P-Visa for Professionals:
If the company needs to sponsor the foreign worker for a specific project requiring specialized skills, a P-visa may be an option.
H-1B Visa:
For certain technical roles, an H-1B visa could be considered, but this process is more complex and requires employer sponsorship.
