My answering this question does not form an attorney-client relationship. Always retain a qualified attorney before taking any action. My office offers free consultations.
When does the I-94 expire? If you travel very close to its expiration without the employer seeking an extension, it will be difficult to convince the Officer upon return that the job offer is still open.
