L1 visa applicability

[BRJ]

I have an L1A visa which is valid from 1 April 2007. Is there a time limit within which I must travel to USA barring which the L1A visa may lapse or expire or get invalidated?

When ever you are traveling on the L1A on behalf of the company you have to carry the required documents (from your company) which mention your need to be in US as these are checked for during Immigration Check at port of entry in the US

Thanks, but my question really is this. My L1A is applicable from 1 April. If I dont travel till say JUne / July would there be a problem? I mean to ask is there a time limit within which the first travel ought to take place to keep the visa valid.
