dear freelance writer,
1. as for the laws. company being registered in US, falls under US laws, regardless where they physically located.bad ting here - impossible to be found:)
2.as for being educated and esl writers, natuve speakers etc - clients sgould worry about quality they get not who "produces" it. u r right, im not a native speaker, but unforunately, im more "grammatically right" in my writing than some native speakers.so my opinion - be the writer from laos, US or Mars, as long as the quality is good and high, i would not care who writes. plus the company is subject to US laws according to registration data.
as for hhhonesty - u r right.it would be much more ethical to tell truth. but everyONE finds his own way to survival:)
