Due to my heritage and usual country of departure, i used to tell immigration officers that i was in the USA to drink beer and get l**d...... this was perfectly acceptable until BA forgot to return my I94 form. Since then i have had "immigration issues" regardless of the fact that teh questioned visa permitted a 90 stay and yet i returned INTO the USA within 40 days!!!!
After 4 visits and assurances that they would fix it, I started to avoid the usa.
Unfortunately, i have to go there next month for the 1st time in 5 years, i certainly have to say that its not by choice....... But if i get hassle it will just mean that the $5 million contract that i"m seeking will go to a European company....
