My Thai husband's spousal sponsorship application was received on January 11, 2017. We have not received a request for medical yet (so 6 months and counting now...). Not sure why it takes so long to request the medical, but Thailand has typically been the second or third longest country for processing time... 80% of all applications are supposed to be processed in less than 12 months, but I wouldn't be surprised if the 20% of special cases that take longer than 12 months is mostly filled up with the countries that have always been very long like Thailand and Afghanistan, etc...
