I have sent off the required paperwork for the 90 day reporting  to Immigration at Chaengwattana Bangkok 

via EMS ( they received  the letter ) with the return stamped envelope 28th May enclosed 

I have had  two done same method no problem sent off 15 days before and received back with in a week 

my 90 day finishing date is the 11th June  

still waiting for the receipt of  the new  90 paperwork from them 

would accept any advice on Options if not received by the 11th

should I wait a few more days have the EMS paperwork as being received  at Chaengwattana  

thankyou 

No need to worry about it since you have proof it was sent and received.

The immigration website states to contact the office if you have not received the receipt within a month.

Thank you ubonjoe for the quick response 

and advice hopefully I will receive the paperwork  soon

regards 

Not to worry, I did the same and my 90 days is up 10 June but still waiting for receipt. I usually get the receipt in the mail on the exact date due or a couple of days after. Never a problem.
