We have also been waiting 5 weeks now. The only request was for insurance receipt and I provided immediately. Despite all the suggestions that BOI are responsive, my experience has been quite the opposite. Either cut and paste response (not specifically addressing the question) or no response at all. Most recently, they ignored my questions regarding health insurance and simply said "no additional documents have been requested". Nothing else. We are with screen 5, FWIW.
I am shipping from Philippines in a month, a 20 ft container with about 26cubic mtrs including two large TVs, some carpets, a Yamaha keyboard. I got customs estimates from two shippers and they were both in the US$800-1400 range. I could likely get the number down by excluding the electronics / keyboard / carpets, but will probably just ship it all. I don't find the amount unreasonable compared to what I was charged on the Philippines move.
I have worldwide (incl USA), high-end insurance coverage through Allianz, not travel insurance. The cost is exorbitant, so I don't really want to add another policy. BOI has responded with cut and paste (or not at all), not tailored to the actual question. I am hoping to hear from someone that actually went through the process with an annual insurance policy such as ours.
Yes, the school was pushing the education / guardian visa for wife & child for initial entry, so investigating options for myself led me to the LTR idea. Might as well do all of us on the same visa, seems worth the cost in terms of immigration hassles alone
