The research aim was to develop a prototype system of the non-immigrant visa, a case study in the Royal Thai Embassy in Vientiane. The System Development Life Cycle (SDLC) concept and agile method were used in this research. The researcher collected the system requirement by studying the documents and interviewing 2 groups of users viz the head of consul and staff including 2 persons. All data had been analyzed for content then summarized the system requirements. These were led to design and create a prototype system. After that, the users tried using the prototype system and evaluated the satisfaction in 3 aspects with a questionnaire consisting of the system performance, the ease to use the system and data security, followed by interviewing. The results found that users required three main issues: (1) the system for data collecting or important notes from government document for a later searching, (2) the barcode for easier information searching, and (3) the information about amount of monthly-classified visa applicants, nationality, and provinces, which are used to define related policies. For the prototype system, it had 4 main processes, i.e. inserting data, searching information, creating barcodes, and creating report. The database system of the prototype system consisted of 17 files. Once the users tested the system and evaluated, it was found that the overall mean of satisfaction scores of the consul head was the highest level with mean of 4.83 and standard deviation of 0.55, while that of the staff was the high level with the mean of 4.17 and standard deviation of 0.72.
