L1上面用的词是work for.. one continuous year...
To qualify for L-1 classification in this category, the employer must:
Have a qualifying relationship with a foreign company (parent company,
branch, subsidiary, or affiliate, collectively referred to as qualifying
organizations); and
Currently be, or will be, doing business as an employer in the United States
and in at least one other country directly or through a qualifying
organization for the duration of the beneficiary’s stay in the United
States as an L-1. While the business must be viable, there is no
requirement that it be engaged in international trade.
Doing business means the regular, systematic, and continuous provision of
goods and/or services by a qualifying organization and does not include the
mere presence of an agent or office of the qualifying organization in the
United States and abroad.
To qualify, the named employee must also:
Generally have been working for a qualifying organization abroad for one
continuous year within the three years immediately preceding his or her
admission to the United States; and
Be seeking to enter the United States to provide services in a specialized
knowledge capacity to a branch of the same employer or one of its qualifying
organizations.
