We headed to the immigration office with my temporary proof of health insurance.
So, we achieved what we wanted with just one visit.
As you may imagine, the immigration office is a huge chaos. In order to ask a question, you need to pay a visit to the office and wait long hours because yes, no one answers the phone.
In addition, there are no signs to navigate ourselves, nobody knows accurate information, and everyone says something different, which greatly tortured us till the end.
