I try to research much as I could about it before I applied and actually trusted the agency but truth be told I could of file it without the agency and feel like the process would be way better. One the agency in Thailand told me one thing an when I got Asia they information was very wrong why I also encourage those actually ask the agency in the country they gonna file and have go to instead the ones in Thailand as each embassy is different and the requirements I been reading different at each one.
