To avoid having your Uruguay visa application rejected, follow these steps:

• Error-free application, Complete the visa application form accurately and completely. False or missing information can lead to rejection.

• Valid passport: Ensure your passport is valid for at least six months from your intended departure date from Uruguay and has sufficient blank pages. If not, renew your passport before applying. 

• Recent photographs: It is important to submit recent passport-sized photographs that meet the specific requirements of the Uruguay immigration authorities. Avoid heavy filters to ensure you look the same way as seen in the photograph.

• Supporting documents: Provide all required supporting documents, such as financial statements, employment and invitation letter (if applicable).

• Travel history: Consular officers often use travel history to assess the consistency and credibility of your application. Failure to mention details of your previous visits to Japan can significantly impact your visa application. 

• Financial proof: You must show that you have sufficient funds to cover your stay in Uruguay. Bank statements, pay slips, or sponsorship letters can serve as proof.

Yes, you can reapply for a Uruguay visa after rejection. However, the ease of reapplying will vary depending on the reasons for rejection:

• If your visa was rejected for minor reasons such as incorrect details or missing documents, reapplying is straightforward. You can correct the errors by providing the missing information or submitting additional documents. After correcting the issues, submit your application again for a higher chance of approval.

• If your visa was rejected for more complicated reasons like previous visa violations or being blacklisted, reapplying can be challenging. In such cases, consider using professional visa services for assistance, as they can guide you through the reapplication process and help address complex issues.
