When did you first enter US with the L visa ?

Dec/14, I have already filed 2 years using HR block because I was not confident enough to do it by myself. Thanks for the question.

Why several people mention 1040NR for non-permanent residents? Is that incorrect?
HR Block used 1040, 8582 and 4562. Should I keep on using the same forms? Does TurboTax support all of them? Thank you again.

With L-visa, the key is if you stay in the US for more than 183 days during the year, please read the above blue link.  Most of those forms are available after 1/25/2018.  Walk through the step by step instructions in the program, it will create the required forms you need.

Perfect, I really appreciate your answers. Thank you!
