Hi Doug,Your employer can file for the Permanent Residency apticiaplon on your behalf as while the E3 visa is not a dual intent visa, it is also not prohibited either like the J1 visa or F1 visa. Many people have successfully got their green card on the E3 visa. I would suggest that maybe your spouse get an E3 visa as well if possible and then have their employer do the green card apticiaplon too as for whatever reason one may be faster than another due to the long processing times and many steps and thus if one gets it, as a spouse you can get a green card as well.Good Luck,CJ
