As an owner of a painting company. I employ people, yes Mexicans, who can provide me a green card and submit to a background check.
Be wary of the paint companies who use subcontractors. The subs often will provide insurance to the employer when “ interviewing” but do not maintain that insurance. Therefore if a sub gets injured on your property YOU THE HOMEOWNER, may have a claim on your insurance. Always ask for the contractors and the sub insurance, if they cannot provide it kick them off the property immediately.
A lot of Mexicans have better work ethic than our traditional Americans but you do open yourself up to huge liability especially if they are illegals.
You would think those Mexicans would be the most against illegals since it cuts into their wages.
