I am a Canadian citizen.
(1) I've heard I am allowed to stay in the states only 6 months every year? BUT HOW CAN THEY CALCULATE THIS 6 MONTHS? From each Jan.? Or from the first time you enter US, then every 6 months is counted as a cycle? Where is the official explanation for this rule? On US immigration's web site? Where's the page link? Thx!
(2) Does US border officer record the day when you enter or leave US? Stamp the day on your passport or just in their computer database? If they know you have lived in US for more than 6 months without visa will you be denied entry permanently in the future when you want to enter until you have a visa? Where is the detailed explanations for this rule?
(3) I am doing some online business like eBay. I recently find it is evident USA is a FAR MORE better place than Canada to conduct such kind of "self-employed" business. As this business has no company, no record, and is tax free, I don't think I can apply any valid visa on this that would permit me to live there long. Any non-job related visa I can apply? Is there any way out?
