LTR Visa- Any need to Leave and Arrive once a year?

[HerewardtheWake]

My LTR visa was granted in April and the existing O-A visa was cancelled.  I know I have to submit a TM-90  form  or something like that once a year. 

 

However, during the the LTR visa validity period, do I have to leave the country once a year and then return to keep the LTR

visa valid? Or can I just stay put for the five years and keep the LTR visa valid without incurring any overstay penalties? Thanks for any insights.

There is no need ever to leave. Apart from the one-year check in that you already mentioned, you just need to do the five-year requalification at the half-way point.

Thanks, Tim.
