did I miss a step here? 1-90 day stay plus one more 90 day stay right after it equals 180 days. Where did you get the other 90 days? If you come in 60-day visa-exempt, extend for 30 more days for a total of 90 and do it a second time, you’ll probably be OK, but the next time you will likely be denied entry. You are not a tourist. You are the person they are trying to keep out.
