If fired on an E3 visa is the employer liable for paying the reasonable cost of transport home? I know this is the case for H1B visas. Is this also true for E3 visas? Is there any legislation someone can point me to?
The rule that you are referring to is covered under INA 214(c)(5)(A) which states:
In the case of an alien who is provided nonimmigrant status under section 1101(a)(15)(H)(i)(b) or 1101(a)(15)(H)(ii)(b) of this title and who is dismissed from employment by the employer before the end of the period of authorized admission, the employer shall be liable for the reasonable costs of return transportation of the alien abroad.
Given that this is specifically with regards to H-1B and H-2B visas, it does not appear that E-3 visas would be covered under this provision.
