If you want 150 days you can do what I just recently did. 60 day visa, 30 day extension, 2 land border runs. You can get another extension after your first visa run if your landlords cool enough to do another TM30 after your border run but my landlord is a slack ass so I did 2 border runs. Either way will be fine for 150 days
Yep. Get your extension during the last week of your 30 day stamp. Do 2 land border runs on your last day of your extension and first border run. Easy done
well if your landlords a prik and doesn't lodge it, immigration fine you and tell you to get the landlord to reimburse you. If the landlord doesn't there's nothing you can do. If this system was fair, the fine would be mailed to the landlord directly which is how it would be done in a western country if they had a similar system
